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

Hey, good idea!

very interesting concept. While it was loading and i was reading the description saying it was an anti-shooter, what I had imagined was not even close lol. Gnar tunes, interesting concept, runs smooth, designs were a little too abstract for me, colors were a little bland 9/10. Thank you for sharing!

I've played this game several times now. I've read every phrase, over and over. I've heard the music again and again. This game is a truly master piece. One of the best games I've played in Newgrounds. To put it simple, it's astonishing.
