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)

(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

Perfect Game

This is one of THE best games i have ever played here i liked the graphics, gameplay, and the multiple quotes used in the game but i found that the final boss happened to be easier then the regular enemies you made but all in all it is the perfect game


Rated 4.5 / 5 stars

quite amazing

very, very difficult.

perhaps make all targets slightly larger? I found that boost was never useful because I was already so fast, it was simply a matter of dodging, while trying to hit them, and any useful triangles I formed were pure accident.

People find this review helpful!

very nice and challenging

i couldn't get far on my first time but after like 3 try's i realized this is a very high quality and fun game, smooth animation, gives you a adrenaline rush and makes you have to be aware of everything. good job and thanks.

Not sure what to say

One of the trippier games on Newgrounds, though it is pretty awesome. The main thing I think I should point out is that the normal boss fight would be REALLY bad for epileptic people with all of the flashing. Just a heads up.
