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)

(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

Was kewl

I actually enjoyed playing that game

great game

really liked it :]


There are some people complaining about dificult, for they "Go play a atari pacmen then!"
The game rocks! Everything, good enemies, trinity attack is cool. I am trying to beat the boss now. Even the phrases in mid game rocks! And it is awesome in keyboard and I could not play it in mouse(many games where you control something with the mouse bugs and are hard to control)
Very thank you for the game!

farking incredible game and addictive!!

good, but a bit hard

Really great game, the style is simple, but yet its very addicting. The music wasn't annoying in fact it was a great choice for this game.
The dialoges are true, no matter from witch point of view i see them. Makes you think a bit about the tihings of life.
The only problem is that i have to start the game again from the very begining of the flash (i hope you know what i mean) instead of the menu.
Anyway keep it up!
