Grey matter is an anti shooter, or a shooter without bullets.
Essentially your the bullet.

Run into the exposed brains of incoming attackers to destroy them.
Killing 3 of the same type of enemy will cause a "Trinity attack" killing everything inside it.

Avoid enemy dangers (flashing bullets, tails, teeth and lazers)

Download the stand alone version here /downloads/flash/greymatt
(it runs faster)

-You can upgrade at any time in game by pressing P or Esc to pause the game.
-Shields are most important and should be purchased first.
-Holding shift will not only slow you down for better control, but it will also extend, and speed up your options that spin around you.
-Trinity Attacks will increase your chain multiplier which gives you more points for upgrades

All the rest of the info is in game

Anti-shooter, it's very addictive, but since I get bored of everything easily don't be sad lol. I just couldn't get into it.

You managed to take something, and add a little twist. And by a little, I mean completely reverse the concept of a shooter. I like things like makes me wonder what are people going to do with this, and you haven't dissapointed me. At all. Gameplay's great, the story (Well...what they had something reminescent of a story, anyway) was great and intriguing, the quotes in there are powerful (To say something, they made me rethink some things, actually.), and the extras?

Love'em. Just love'em. Though I can't seem to beat Expert Mode (It's like a Touhou game, honestly!), the normal game is addictive enough, and the boss? Nice. Just...nice. *thumbs up* My only complaint is lack of any harder enemies (All of them could be obliterated with one blow, but that was probably your intention), and the rather...I dunno, medium hard difficulty (To which many have complained). Some more enemies and firepower, as well as new weapons to be used AGAINST you would be nice, the bullets and LAZORZ aside...that is, if a sequel is in the works (But if there isn't, I'm fine. It seems like a good standalone game, but a sequel...well, people will be asking for one, but it's your decision.). All in all, great job, keep up the great work!

I did enjoy it but maybe a lower difficulty setting!!!


Rated 4.5 / 5 stars


even though it takes patience to get to the very end, this is one of the most interesting premises I have seen...


Rated 4.5 / 5 stars

this is right!

see if you beat this you are good, if you beat expert you are a very fast and tough thinker who can probably think past alot of other flash games, extremly challenging yet it is still slightly beatable cause ive done it already...
