  1. The play mechanics are well realized and thankfully add something new the to genre. If you're a Metal Gear fan, the card collection aspect alone will make it worth you time for nostalgia's sake.
  2. The most interesting features I found were the cost system, which determines the relative order of actions in the game, and the equipment bonuses, which can vary depending on how you equip each item in relation to another item.
  3. A great game with superb graphics, game play and re-playability.
  4. If you love card games or are a fanatic for Metal Gear, and you're fairly patient, then this could easily be the game for you. It's a really great implementation of new technology as well as being very ambitious.
  5. Easily one of the best turn-based strategy games to come along in years. It offers a deep and flexible system of deck building and card playing, and, better still, it contains everything that has made the Metal Gear franchise so popular over the years.
  6. The experience is analogous to an elaborate board game in which the board and architecture change from mission to mission—much like Hero's Quest (fantasy setting notwithstanding). It may not be a typical Metal Gear title, but it is a very robust game and it is worth a look for those yearning for something different.

    8 / 9 / 8 / 9 - 34 gold [Dec 2004]
  8. The graphics are stunning, the sound is incredible - this is definitely Metal Gear, just with cards. Whatever you do, don't ignore the importance of this game to the early life of the Playstation Portable. [JPN Import]
  9. 85
    This game is great precisely because it's an original take on a familiar world.
  10. While Metal Gear Acid is an amazing title which strategy fans and hardcore MG addicts will appreciate and love, it cannot be recommended to everyone. This is a niche title that is perfectly suited for the handheld console, but which may be too slowly paced and strategic for most - add to that the initial learning curve of the card system.
  11. A rewarding experience that rewards the player for how well they play in a stage, and with an intruguing storyline.
  12. Game Informer
    Snake has made a surprisingly smooth transition into the world of turn-based combat. [May 2005, p.126]
  13. Once you get a handle on the core mechanics, you'll find in Acid a rewarding game of strategic stealth combat coupled with a quirky, intriguing storyline and some neat points of nostalgia for the longtime Metal Gear fan.
  14. Those who stick with the game will get used to this new style of gameplay. As far as strategy games go, this one is chock full of action and just a few of the things we love about the series.
  15. Fans of previous Metal Gear stealth adventures will have to adjust their tolerance level to ‘HIGH’ to deal with MGA’s insanely hard and complex new turn-based card system.
  16. 80
    A fascinating, unusual combination of turn-based story-driven missions with "card-battle" mechanics (think "Magic the Gathering" or "Yu-Gi-Oh!"). And being part of the infamous Metal Gear franchise, it's got all the convoluted yet strangely intriguing plot twists you'd expect.
  17. 80
    A highly enjoyable tactical espionage adventure that forces you to think in new and exciting ways. It's also a sweet puzzle game, a card-based strategy title that takes familiar (albeit stale) gameplay mechanics and breathes life into them.
  18. Now it's not going to be as exciting as a full-on Metal Gear game, but to be honest, for a card-based strategy game, this is really a fun game that can be quite rewarding.
  19. I dig the card thing and all, but I would have loved to play a Metal Gear Solid game that stays true to the PS2 games.
  20. PSM Magazine
    It's also tense and well-balanced and the diverse selection of cards you can put into your deck enables deep customization. [May 2005, p.80]
  21. Official U.S. Playstation Magazine
    As solid as the turn-based gameplay is, I still have to warn you that your brain might fold in half as it comprehends how the game works. [May 2005, p.114]
  22. 80
    Tactical stealth using cards? Not everyone will like it, and some will hate it, but for those who can get around it, a great gaming experience awaits.
  23. Card gameplay has some good moments but eventually just becomes monotonous.
  24. Electronic Gaming Monthly
    Give this one a try to experience something truly different, though be warned, it's a seriously hardcore game. [May 2005, p.90]
  25. Packing in all the strategy of chess and infused with the goodness that is Metal Gear, this could be the sleeper hit of the PSP.
  26. Don’t get me wrong, I’d choose real-time play over card battles any day, but that doesn’t change the fact that Acid is a unique, strategic approach to the Metal Gear universe, with enough depth to keep you coming back for more.
  27. While it's not what I'm used to from the "Metal Gear" franchise, these brain-straining battles are very rewarding, mainly because you invest a great deal of time in planning and methodical movement.
  28. There is fun to be had with Acid. It takes some patience to get there, but once you do, it feels like everything was worth it.
  29. It's extremely unfortunate that the Ac!d team couldn't reshape the opening hours into something more welcoming and tolerable.
  30. 70
    Wireless multiplayer mode (only available in the U.S. version) pits two players head-to-head, but this option is unlockable only after several hours of play (that may be too long for many players).
  31. 70
    At best, Acid is a really fun time for a very small percentage of gamers. At worst, it's a good game that a lot of people will find boring.
  32. The card battle experiment was a novel one, but the result is an unbalanced, unforgiving mess that will test your patience while you try to piece through a convoluted story. Strategy fans may dig it, but everyone else will do well to stay away.
  33. Play Magazine
    As expected, the story is completely convoluted, but the twists are still surprising (if not infuriating), resulting in a worthy but very different addition to the franchise. [May 2005, p.67]
  34. It's turned my head, even if it's not quite the 'trip' that it might have been.
  35. Pelaaja (Finland)
    Acid is an interesting new direction for the Metal Gear series. Real time stealth action transforms into a turn based strategy game. The card mechanic, collecting more cards and adjusting your deck keeps player coming back to the action level after level. Still, the story is not on par with other Metal Gear games and playing the game can be an slow and sometimes boring experience. [Sept 2005, p.63]
  36. AceGamez
    Personally, I enjoyed the gameplay and story and upon completing it I was left with both satisfaction and the want for more.
  37. It’s also a very original title - you don’t see too many turn-based stealth/strategy games, and we respect the fact that Konami took a big risk with their flagship franchise in an attempt to deliver a true PSP-only game.
  38. 65
    It's cerebral and requires special attention, but that might not necessarily be fun -- all that hot PSP technology, just for an experience that's as graceful as a banana slug.
  39. As a game by itself, Metal Gear Acid is alright. But as a Metal Gear game of the series, I much rather prefer the intense action of a third person real time adventure game.
  40. In refusing to let the PSP’s home-console-style graphical capabilities dictate the nature of its gameplay, Acid is a valuable blueprint for future PSP development. [Feb 2005, p.77]
  41. Metal Gear's move from all-out action to turn-based strategy has been handled with style. [JPN Import]
  42. 60
    Two things ruin it though; the first is that the seeming blank refusal of the designers to refit the game's format so that it works as a card game. The second is that it's simply dogged by so many wincingly schoolboyish mistakes that it would be unconscionable to score it higher than that "Buy by all means but be forewarned" number six. [JPN Import]
  43. games(TM)
    While the card and strategy elements work surprisingly well, they don’t really fit the stealth side of the game for which the series is so highly regarded. [June 2005, p.112]
  44. 60
    Fans of turn based strategy games will enjoy this title though, if you aren't a fan then I suggest avoiding this title.
  45. Metal Gear Acid is a decent tactical card battling game, but it is not a true Metal Gear title, and for me I expect no less.

As Turn Based is a dying genre I'm glad they created Metal Gear Acid (and part 2). Storyline is good (8/10), graphics are quite good for a handheld (8/10) and gameplay is where this game shines (10/10). Winning cards and completing a good deck makes the game with a high replayability value. Custom missions with 'kill all enemies' takes a complete different deck then 'stay undetected'. Glad to have found the origional game in the stores today cause it really makes my collection of games for the PSP complete. Full Review »
