  1. Minor quibbles aside, this is a must-play game for action gamers, especially those who enjoy playing cooperatively online.

    Totally free, and totally worth your time. [Oct 2010, p.65]
  3. Left 4 Dead minus the Zombies, plus a truckload of skittering aliens. Pure brilliance, and free to boot? Valve knows how to make their customers happy. Get to downloading it, stat!
  4. Download Alien Swarm. Do it, it's an order. It's one of the best freeware games of all times. It's fun, addictive and has great growth possibilities considering how actively the Steam community is already working on it. Thanks for the gift Valve, we love it.
  5. Left 4 Dead top down! Alien Swarm is fast-paced, alien-filled fun that demands cooperative gaming and delivers cleverly directed missions that stay challenging from beginning to the end. The upgrade systems serves as a motivator and the match making is quite good. Physics, sound and lighting convey a spooky atmosphere. Although there is only one campaign at release, Alien Swarm delivers more fun than most full-price games.
  6. Despite the issues of repetition and somewhat contrary design choices, Alien Swarm is an enjoyable shooter at an absolute steal of a non-price.
  7. At least Alien Swarm doesn't try to be anything other than what it is. It's an online action shooter with plenty of things to shoot at.

It runs on the SourceThis game, while small, is a great game from Valve that's like a top down version of Left4Dead except with alien bugs. It runs on the Source engine and enables people to make their own maps which is a plus. I like how weapons are unlockable but the default weapons still can stand a good chance against enemies on higher difficulties. Overall, it's free and I can't think of a reason not to buy it! Valve sure knows how to cater it's fans with free little gems like this game. Expand

Higher difficulties are challenging, but always fun. It mostly lacks re-playability, as the same strategies tend to work despite where and when the enemy may spawn. The game is short but its more than what I expected. On top of that, its free. Expand

    This is a very good and fun game to play with your friends! Heavily inspired by the 2nd Aliens movie, it takes all the best from that sci-fiThis is a very good and fun game to play with your friends! Heavily inspired by the 2nd Aliens movie, it takes all the best from that sci-fi Aliens-like lore. The execution of the game's storyline is nice and of the gameplay elements just brilliant, powered by the Source engine. It plays as a top-down view 4-player co-op tactical shooter. There are 4 well designed classes of marines, each with its strengths and weaknesses: Sarge, Weapons Specialist, Tech and Medic. You'll need each of them, so the game inuitively encourages the co-op of 4 friends and is at its best in that. As you play and work together you will feel engaged and rewarded for cooperating and coordinating with each other. The campaign has a good pace with multiple missions and a nice variety of objectives and situations, like those you would expect from the Aliens series. Before each mission there's a briefing screen when you can review the map and objectives and select the best gear for it. There's also lots of weapons and items to unlock as you level up. There are some really nice touches, like being able to draw on the mission map with your mouse, either in the briefing or during missions, to help plan and coordinate strategies, or reviewing your performance after a mission with different charts and an animation of the teams progress on the map. Connecting your friends together in the same game is effortless via the main menu. It lets you create public or friend-only games and lists friends playing and friend-created games available, which you can join with a click - no dedicated servers needed nor ip details. The only downsides I found are that the in-game voice chat support had some noise and that there is only one official campaign. But you can always use skype for voice chat and there are more fantastic fan-made maps and campaigns, like for instance the MapPack 1.2 which you can easily find. All in all, an amazing free to play game with lots of fun to be had especially in a group of 4 friends. Expand

    Hey, that's a good game. What makes this game even more fun? ITS FREE! You can download, hate, and throw away if you don't like it. But i'mHey, that's a good game. What makes this game even more fun? ITS FREE! You can download, hate, and throw away if you don't like it. But i'm sure you won't do that. This coop top-down game is fun, although is quite short (the official campaign is short but there is lots of unofficial maps {but they do not give xp or any achievements}) but in compensation there is a great arsenal of weapons that make the game more attractive. Recently a AI director has been added to the game to you never play the same mission, what was cool, but didn't help, the game is still repetitive and boring when you finish the campaign 4 or 5 times.
