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

Rated 0.5 / 5 stars


the seizure-color bullets are nearly impossible to actually track, making it artificially difficult to avoid them. fake difficulty much? I hated the gameplay and the graphics give me a migraine. horrid experience.


Rated 3.5 / 5 stars

Terrible controls with keyboard. Your guy zips around the screen and seems to only be able to go forward sideways and back. Cant the left and right keys rotate him? I think this game is overrated, although the music is good.
