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

i liked how u didn't shoot anything to kill the enemies. to be good inthe game you have to react fast and be good with triangles which is something new and i liked it.

Do Want

This game was amazing. owo The graphics are amazing, the gameplay is awesome, and the music is downright badass. I've played through three times, this review being written after my third playthrough, and it gives me a reason to be late for school.


Rated 5 / 5 stars

Possible one of my favorite anti-shooters

One of the best Flash based games ever! i loved the scripts and gameplay was just all out perfect. Just one thing i wanted, A story behind all of this. Is the grey matter finally at peace? does he return home?

Anyway, 10/10
