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

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...

Rated 5 / 5 stars

I love it

I'm honestly so tired of the some old games where you move about and shoot things... and if they hit you, you die... This is COMPLETELY reversed! I love ramming the shit out of things, and there's no shooting!... maybe it's because I am a crappy shot and I run into things easily... but I love this! Good job! Really innovative! And what a nice way to do something new. 10/10 :)
