@kambous and gish1 - It's not a hack, or an achievement. It's a cheat code used in most Japan video games (In Japan, it's known as the Konami Command) and possibly other games/sites. If you type it in on the Marvel website, a giant chipmunk pops up. If you type it in on facebook, there is a glare when you scroll / click on things.
Bad game... There is a blind spot where bullets can't go, so this game is basically holding down the "A" key... So this isn't even a game. Gameplay is too slow... Way too slow. There is no music, only the small clicks when a bullet hits a ship, which is very annoying, and there is no mute button. 1/5, looks someone's first game, where they are testing something.
Thank-you, Tukkun. And sorry if it seems I'm assuming you don't take time to try your best, but really. This game has gotten too childish, and it just doesn't fit in with Kongregate anymore. Thanks for the memories, though.
All updates after the fixed bonus bar are terrible. Changed from 5/5 to 1/5, undid my favourite, and I'm quitting, since it appears Tukkun no longer cares about his players. It's sad the new players won't be able to play the good AI:The Game
Tukkun, please change the screen for buying boosts... Change it back to how it used to be. How it is now is childish and hurts my eyes. Makes me really want to quit
