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

-Edmund & Tommy

well then

that was a new experience, i liked the part where it said "take your meds" lol but anyway, it was very hard, those ones with the tails should turn slower or stop to turn, cos they wiped my out of lives completely, even if i was going slow with an option(<-- what does this mean? confused me :P) anyways, good going and keepy up :D

It's not aimless running around ya know

This game is pretty amazing , quite innovative IMO since I had only play shooting games and not anti-shooting !

For the snake-like monster , just use shift , slow yourself , get close so your option ( if you don't have any , use yourself) to kill it .

The game pretty hard wat the heck . 9 stars

Was good for about 20 seconds. Once you realize how horrible the keyboard controls are its game over.

Super Fun!

This game is very fun and original! It's a nice twist to just shooting people. All the enemies were very original and different and I like the medicine you can take. This game is quite hard though, which is good and bad. Good in the sense that you don't just get bored but annoying that you can never pass a part you're stuck on. I think the snake (with the glowing tail) is should have a bigger head because you miss a lot when trying to hit it... Sometimes, this game is just fun trying to dodge the hundred bullets targeted at you ;-) Thanks for making this incredibly addictive and original game!
