Very mediocre for a tower defense game. There are far better Flash games available in the genre for free, as well as custom games for Warcraft 3. The game just doesn't have the depth to make it very interesting. The visuals are nice, and if you like eye candy then this game might be what you're looking for. However, if you're looking for engaging TD gameplay, look elsewhere.

I am a big fan of the Tower Defense genera. At first glance this looks like a great concept. Very good eyecandy and interesting storyline that you usually don't find in the TD games online. It also has a very well balanced variety of monsters and Towers that allow for all sorts of strategies. (GAME TIP: Although in the end I found that CANNONS and COMMAND towers were the strategy that would get me through. The AI tended to rely heavily on shielded, hidden monsters that only were susceptible to those two tower types) Unfortunately Replay value is next to nill. There are only 25 levels, with at most 30 waves in each. The Grinder Mode (99 levels) which could have expanded the replay value into the hundreds of hours is BOGUS. After wave 30 or 31 the monsters just repeat the same wave over and over and over with no change. If you have built correctly, you can leave your computer after level 32 and not come back until the 99th. In short, this could have been great, and really has the edge in graphics and storyline, but there are so many TD games online for free with much better replay value. If you find this in the bargain bin, its worth about 8 hours of play. I got it for $2.99 which was about the right price.… Expand

It's just another tower defense game. Meaning.. you can play basically the same game online for free. It has better graphics, it actually has a story but all-in-all same game play, and same types of towers. It took me about eight hours to beat it so it has a decently long campaign, little replayability although different modes do add to the fun. In the end, it is a fun game, but in reality you're paying for something you don't have to. It provides nothing more (besides a **** story) than an online TD game. Another bummer is that the towers seem to be unbalanced. More expensive towers aren't necessarily worth the money and by the end of the game I was using the same couple of towers in mass. Buy this game if you love TD's and you can get it for two or three bucks but other than that, play VR tower defense.… Expand

An excellent tower defense game; good visuals, sounds and even voice acting. The campaign mode is a joy to play, it has a unique and interesting storyline that will make you want to continue playing to see how the story unfolds. Unfortunately, the same can not be said of the lackluster, money grubbing DLC; no story line, no new enemies, no new turrets and an inclination to not give the player much (sometimes any) freedom of choice when it comes to creating path ways. Play this game for the campaign, forget about the DLC.… Expand

Good game but it does nothing to distinguish itself from the numerous other tower defense games out there. It can keep you busy and it's not a horrible game by any means. But there are better tower defense games out there. However the graphics and voice acting are very well done, which bumps the score up from average to just barely above-average for me. It's not a bad game by any means and buying it won't set you back too much but you can easily find a better tower defense game out there for the same amount of money.… Expand

I am a fan of the genre, but have stuck to the free TD games in past. This is the first one I've actually paid money for, and it was worth every cent. First, it's beautiful; second, it's well balanced -- fun for the novice TD player as well as an expert one like me. I loved the challenge modes too - great fun. Nice work, Hidden Path!!

Sehr spaßiges Spiel mit Suchtfaktor, gerade wenn der Schwierigkeitsgrad steigt und die letzten Level nahen. Logisch Denken zu können ist eine Voraussetzung, wie vorauszuplanen um die meist knappen ressourcen optimal einzusetzen. Alle 10 Türme die das Spiel bietet haben einzigartige fähigkeiten und müssen situationsbedingt und Levelabhängig platziert werden, manchmal muss auch für die anstürmenden Gegner-Horden ein Irrgarten gebaut werden, um einen möglichst langen Weg zu erschaffen und das erreichen der eigenen "Basis", den Power-Cores, herauszuzögern und dabei möglichst viel Schaden anrichten zu können. Doch vorsicht: Manche gegner rufen verstärkung, andere sind getarnt oder vom einem leistungsfähigen Schild umgeben. Alles in allem ist dieses Spiel sein Geld mehr als Wert, wenn man dieses genre mag.… Expand

Wow, just wow. Love this game! Think I found my new favorite genre :) Now all I need is an expansion with more maps, hehe. I sat down and couldn't stop playing this until it was finished. Might actually purchase this a second time when it releases on 360 just to support the developer and pick up some gamerscore.

I'm not much into the Tower Defense games but this is by far the best one I have ever played. I like the idea of having some control over the paths of your enemy and being able to direct them to their demise. It was easy to learn and the visuals are good. Even after completing it, I still go back to see if I can do better on some levels. For something not to intense and relaxing, Defense Grid is the game.… Expand

It's a good fun game which requires timing and strategy to get the best scores which adds depth if you like leaderboards, cause the more resources you have the more interest you get, each tower also loses 25% value once built so you need to minimize your spending and build at the last second for the best scores. The leaderboards however have some hackers on them, i would wait for xbox 360 version.… Expand

This is a great game with a lot of replay options due to tower placement, weapons selection and timing. It is very engrossing, immersive and just plain fun. It's somewhat of a chess game, of sorts, as you have to plan your offensive and defensive strategies in real time. All the above plus nice visuals and voice acting make it a winner in my book.

Considering the price and what you get, this game is a worthy collection to your hard drive. Some will finish every level and leave. Others will get the most out of it, trying to get high on the Leaderboard (online score board to your friends and rest of the world). This is where the game shines and you soon realize, to be a master of a map takes some thought. Every map looks great and the game play works really well. The "speed up time" button is a worthy addition too. There are some things that still need work. Some of the mod's for the game such as "Grind" (99 levels of continuous spawns) is far too easy and needs to have a major update. Challenge mode (levels on hard) has to be the most fun and getting a high score here or beating friends is what keeps me occupied.… Expand

Defense Grid is a worthy retail version of classic Tower defense that belongs in anyone's Digital Locker. However, its only a tower defense game, and aside from visuals and 'power spheres' and a talking computer to keep your attention, it still fails to bring anything revolutionary to the genre. A map/game editing tool would have made the purchase seem a bit more worthwhile.

This is a new and innovative take on tower defense games. Yes, there are some nice visuals, but even deeper than that, as you progress you'll find this is no run of the mill Flash TD game. You're forced to come up with effective ways not only to kill the oncoming horde of creeps, but how to route them and stall them, and there's not just one simple solution to every map. Several different challenge levels for each map and an achievement system give this title plenty of replay value. This game would be upgraded to a 10 if a map editor were ever to be included.… Expand

I played this for a couple of days before completing it. It was very addictive until I completed it. Once you figured out which towers to use, it was quite easy. Some of the towers are pretty useless and I am sure they are just there to add a bit of variety. The graphics are excellent and if you don't mind the price for a couple of days play then it is worth it.

Best game of its type, for $20. For so little money I got so many hours of game play. The variety of towers makes the game and forces you to employ strategy as well as brute force. The aliens walk a path and you either have to pummel them to death or shape their path then pummel them to death. Seriously you will not be going to sleep the first night you get this game...So don't download cause you'll probably get fired from work. … Expand

I've been waiting for a game like this for a long time. Playing Tower Defense maps in Starcraft was great, but this takes it to the next level. There is a decent balance for all the weapons. I found the first couple levels can be tough until the game unlocks more towers, then it is a blast to play. A nice touch putting in the Challenge mode to really test you.

This game is not just tower defense. It comes with an enthralling narrative that most games would struggle to match, never mind one that is based upon an old classic without any sort of story! The game play is highly addictive and leaves you constantly coming back for more. Get it for £3.50 on Steam while you can.

I've been playing lots of tower defense games lately, First Pixel Junk Monsters, then Savage Moon also on the PS3. Now I have Defense Grid for my PC and I'm hooked. The load times are seriously quick, being able to backup a minute or so to correct recent mistakes is genius, the graphics are well done. The only thing I would like to see added is the ability to swivel the camera around the battlefield.… Expand

Deeply strategic game with surprisingly gorgeous graphics. Insanely addictive, and refreshingly good voice acting. Control is a little wonky, but isn't a problem once you become accustomed to it.

Addictive and well done. Replayed on harder levels. Wish there was even more levels or add on pack!

This game is solid and had me in it's grip from the start. Each level forces you towards thinking more strategically as the levels get tougher. Defend or die ! .....going down in ...five....four....three...

Warning: This game can be addictive. I didn't realize how badly until Steam told me how many hours I had dropped of my life into the game. While the initial Storyline will take 2 or 3 days to play through, it is the replay value with the various challenge modes and the leaderboards that will suck you in to constantly rework your strategy on the maps. I would have gave it a 10, except for the kind of odd user interface that troubled me on more than one occasion and strong wish for more maps that still remains unanswered. In terms of value, this game places a strong second to PvZ and cements my newly found love for casual games. Here's hoping for a repeat in the near future.… Expand

I'm not a fan of tower defense games in general, but this game just might make me a convert. I have all the excitement of an RTS without the resource management and attention deficit anxiety associated with said RTSs. Learning how to use the units is essential Defense Grid, and it certainly can be a nail-biter when you're running close to one powercore left. It satisfies all my quick impulse playing requirements, but I can get lost in the game for hours if I want to as well. Graphics are amazing for such a simple game, as the low poly counts make for decent gameplay on lower spec'd systems. Get this game!… Expand

I hate the tower defense genre, both what i've experienced in modded blizzard RTS games and random internet flash games. This game is far superior to any tower defense game you will find because of the level of customization and variety of strategies. Whereas most tower defense games involve jamming corners full of whatever the best available tower is, this game employs real geometry: most towers need line of site to fire, requiring the player to throughly scout a map before building. Many maps also have large open tile sections, meaning the player must create the best possible enemy path using the right kind of towers. Combining all that, this game is as much a puzzle game as a tower defense game, and like a puzzle game, finding the right combination of towers is very satisfying. All towers can be upgraded and have performance well-balanced to price. The control system will at first feel extremely non-intuitive: the player does not have a free cursor, but rather a fixed reticle at the center of the screen. Every movement of the mouse moves the camera; the camera cannot be fixed in place with the player able to click on enemies and towers. The camera also cannot be rotated. This slows down the player considerably, but the gameplay does not really call for rapid buying and selling of towers like a lot of tower defense games do. The mouse scroll uses a ton of acceleration, so pick a setting that feels right. The most frustrating thing is probably the lack of hotkeys for building: the player must scroll using up/down keys or the mouse to select from about 10 towers after entering the buy screen, and the selection response can be a bit delayed. When in a hurry, it is too easy to accidentally build the wrong tower, but a little attention overcomes this. I bought this for $2.50 on steam during a sale and it was a steal for that price. GOOD = price, depth. BAD = fixed camera.… Expand

This is just marvelous! It is an excellent little game, and I am not a fan of Tower Defense - but because you towers cannot be destroyed, and you seldom have the option of creating a maze to slow down the waves, it just becomes an excellent little action-puzzle. Comes highly recommended.

Very fun, strong, challenging game. Learning each level can take some time, and determining the proper tower usage takes some forethought. Overall a very high quality game.

Even if you don't know what tower defense games are, this game will have you hook, line and sinker. It's an incredible title and well worth the budget prices you find it for.

If you like tower defense you will like this one. For the price you can get it on steam ,it's a steal.

Simple, Fantastic game. Way too short anyway.... needs desperately more content...

Plays out very strategic and balanced. The levels progress very interestingly and always offer different strategical elements. The game proves very tough. The replay value is pretty low, once youve seen a level you may hunt several medals or play it in different modes, but once you find a tactic it isnt as interesting as first playing it. Alien waves become stronger over time. There is a "endless" mode for certain levels, but once past the "normal" length the strategical balance is lost. That means, Aliens dont become stronger, and your Towers are upgraded to the max, gameplay is getting zero. Essentially ,the game is real good, but short.… Expand

One of the best tower defense games, ever, period. I don't like making such 'profound' statements, but this game has been my favorite of all time since i first picked it up over a year ago. The game has great graphics, good voice over acting, a solid story for a tower defense game, and extreme replay value. This tower defense game has paths that are predetermined and you just have to build towers to kill them as they pass, areas where you can create mazes, and also areas where you can force them to take different routes altogether. As far as vareity goes, this has game has plenty of it. Lastly, one of my favorite features is the point system, which rewards players for spending less money, and therefor being more effecient. So, if you have competitive friends, and think you are better than them.... its a good place to show it. Conclusion: A must for anyone who claims to like tower defense games. The solid amount levels, and gameplay modes allows the game to remain entertaing for a very lengthy time.… Expand

Neat little game that got me addicted for a few weeks, sometimes spending hours on a single level searching for the optimal solution. Happy to have it in my Steam collection.

Perhaps the best Tower Defense there is. A bit too easy if all you care about is beating the game, but can give you a nice challenge if you try to maximize your score and play the other game modes. Surprisingly good presentation for this genre, complete with decent voice acting and a nice storytelling that gives life to the game without getting in the way of it. Some 8h of gameplay if you just want to beat the storymode, many dozen hours if you're a score perfectionist.… Expand

I love this game! The environment, vocal narration, and music successfully set the mood for the entire game. As a newbie, it was really easy to pick-up and learn. The layout of the levels make it seem more like an actual puzzle at times, and it offers up lots of various ways to build defenses and replay the different maps. I have an older video card, yet with the proper configuration, the game still looks great and runs smooth! The only reason I dont give this game a ten, is because I want more... I played through the entire game in basically one sitting. More maps, more aliens, more options - a little more would have made it perfect.… Expand

I'm a minor fan of Defense games, but Defense Grid is absolutely tremendous! It's so well-devised, has great graphics, and the best voice actor ever! For the price, this game is a great value. It's got lots of fun extra modes for each level which is nice as well. Overall, this is the blueprint for how to create a defense game. Truly worthy of universal acclaim.

I was never really a big fan of the tower defense genre until I played Defense Grid. The developers have really done everything right to make it addictively enjoyable. It provides a wealth of different game modes on top of its great story mode. But what really sets it apart from the competition is the extremely intuitive user interface--it is literally just one click control for everything and has a great tutorial approach. I definitely recommend picking this one up.… Expand

Excellent tower defense strategy game. Not sure about the DLC, but it took me about 15 hours to beat the base game's campaign and bonus levels on regular difficulty. While the graphics are a bit drab, the gameplay is smart, challenging, and addictive. The voice acting gives the game a bit of character, and the music and sound effects are solid. Overall a solid package. I'd love to see a sequel with improved visuals, as they are the main thing holding the game back.… Expand

This game does exactly what is has set out to do perfectly. I used to enjoy TD mods on Warcraft 3, so it was a real joy to find this and I'm having fun playing it.

Highly recommended. Voice acting is surprisingly good for a indie game. Huge maps collection with addition DLCs maps pack. One of the best TD game I ever played. money well spent!! if they have implemented multiplayer, this would be the perfect standalone TD game in existent

Very simple tower defense game. The variation of modes and maps, aliens and towers, combinations etc. make this game a credible pay-toplay game. It's so arcade and easy to play yet it can be infinitely complex depending on what you want to acheive. Certainly worth a try.

A classic that has yet to be outdone. The attention to detail, engaging game-play, sound and voice acting, all nicely combine to easily lift Defense Grid to reigning king of the TD genre. Now if they can just port this over to the iPad, I'll be all set.

One of the best tower defense games I've ever played. There are many levels and campaigns to choose from, and a lot of towers/upgrades purchasable to defeat the enemy. A lot of fun when you're looking for something to do.

An absolutely superb tower defense game. Levels require a higher level of intelligent strategy as you progress and there are many ways to play many of the more difficult levels. Highly addictive and a great challenge!

From the beginning, beautiful graphics and a fluid camera with depth-changability sets this game up as a step above the rest. Then throw in a diverse array of maps with space for tons of different strategic design ideas, about 10 turrets with upgrades reflected in design and projectile type, and you've got a great single player campaign. The voice acting is a 6 or 7, about as good as any modern AAA title gets, but the coherence of the story is about an 8.5, and the voice isn't at all what ends up carrying it. About a dozen maps, then DLC that is cheap and offers infinitely unique new options and maps, ie, the open square designed level with two entrances and one exit. This game is still receiving updates and it's been pretty bug free from the start, no crashes or freezes for me, over 80 hours on two pcs. The campaign and DLC now also have CHALLENGE modes which are true to their title, and I'm having all kinds of fun finding out how un-pro all the tactics I barely scraped by with before ended up being. The better to think new solutions! It is the essence of strategy gaming, and this game is implemented very well with lots of content and plenty of replay value, some of the best I've seen from a single player indie/strategy title, and definitely the best tower defense game I've ever played this long.… Expand

Fantastic game! By the looks of it, I never thought I'd find myself playing this kind of game, but it sort of has the "plants vs zombies" feel to it. The point is to stop the enemy form getting to the end, and as you progress you get a variety of better weapons and upgrades to do it with. In the meantime, the aliens (or zombies if you prefer) are also starting to range in types, from stronger to faster; from slow to ones that fly. All around, this game is fantastic and I can't believe it got a measly 81/100, I'd give it a solid 9.5 just because it's plain fun!… Expand

This game can be best described in one word: frustrating. It's simply too difficult and with no way to adjust the difficulty setting the game rapidly becomes unplayable for all but the most hardcore gamers. If you want a challenge, then this is the game for you. If you just want to have fun, then save your money for something else.

Easily the best Tower Defence game ever made. I can't even come up with any cons here, because everything about it was excellent. The DLC's are very solid either, especially You Monster.

i have play a more than 50 free tower defense games and well i have buy this coz i am fan of this type of games but this one its not a game for buying it c mon wake up this is a good game but it doesnt have anything special from the free ones exept the voice and some funny story ! u need to play 9 euro and then more for the dlc ?!?!?! u can buy dungeon defense orcs must die and a lot of other games on that price u can find a lot of games like this on the internet browser and better than this this is the tower defense for ppl who got the money.......… Expand

Very good game for the price you cannot fault it, good graphics and plays nice and smooth with no glitches, I didnt expect much at the price but was pleasantly suprised, this is a great tower defense game.

Excellent tower defense game. This is even more fun than bubble tanks was. Excellent gameplay and graphics. The British computer gets annoying after a while, but so be it. Still a fantastic game with very creative maps.

If you are looking for great relaxing game you got it. If you are looking for challenge you got it, again. What i'm mean, is that game can give you a great time of slaughtering legions of aliens with good balanced and designed turrets, although good soundtrack, nice graphics and easy controls. About bad in this game, is that when you learn all kinda tricks in game you can get boring, but that can be fixed by download content, if you like the original game.… Expand

I'm a big fan of Tower Defense games. That being said, Defense Grid: TA is one of the best I've ever played. It's simple yet clever design allows the player infinite possibilities for strategies. The enemies come in several distinct variations and the level designs vary in sizes and terrain. The AI voice over is simply terrific as he adds levels of humanity to the stakes. The controls are fluid and simple and the music is great but a tad repetitive. There are several DLC that can be purchased so after The Awakening story is completed you can keep playing. It's a true gem.… Expand

Currently the best standalone tower defence game you can buy. The voice acting and narration are spot on and it provides a substantial amount of levels, towers and basic tower defence game play. A must buy for tower defense fans, but still leaps and bounds behind the quality of TD games available through Warcraft III.

After 3 years out Defense Grid is still probably the best true tower defense game out there. Still receiving love from developers in patches and newly added content even after such a long time. If you love tower defense genre, you will enjoy this game from top down.

Ah, raspberries....how I love them. :P For a tower defense game, the voice acting here is amazing, and helps create an enjoyable game world. The gameplay itself is highly addictive and rewarding, with lots of towers that are actually worth building, and several fun challenge modes that help provide variety. I actually think that this is the best tower defense game that I have played so far, but it still left me wanting a little bit more from it (and not just more levels or "modes" or anything like that).… Expand
