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 stars

Good, but

Why not make it for a mouse? Made it pretty tough to play with a keyboard. Other than that not a bad idea.


Rated 4.5 / 5 stars

I love the game but it's too hard!

For me, at least. I can't get very far. But it's a good game.


Rated 5 / 5 stars

Very Imaginative!

A solid little anti-shooter. Extremely entertaining and addictive. The trinity attacks add strategy to the game and make it feel more like a puzzle game than a shooter, but that's not a bad thing!

It's going in my favorites!
