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)

-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

Great Concept, Great Game, Its a MUST PLAY!

I have to admit, its hard to find a game that you can find yourself playing for a long time. This game was it. I found myself a little lost and confused at first but after playing for a few minutes I found myself enjoying the fast pace game play and its simple but beautiful graphics. A big plus for me while playing was the ability to plug in and use my Xbox 360 controller. The music was nice but it did get a little annoying after awhile and I felt a very odd familiarity about the quotes between deaths (call of duty games for one example.) All in all I would suggest to anyone and everyone to play this game and enjoy it!
