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 3.5 / 5 stars

not bad

good game pretty smart but its too hard i think you should make it easyer and music kinda sucks other then that realy good alot of enemy types and strikes and ohh you should put more upgrades like slowing time when slowing the thingie you control


Rated 5 / 5 stars

Good game

It's very challenging and you really have to think everything through before you run in and attack though if you think to long you end up dead, I also think it's cool that you can play it with an Xbox controler (though I don't have one XD) 10/10 and 5/5
