use the mouse to move, arrow keys to aim(left,right), shoot(up), and change weapons(Down). You have two assists/gears(z,x) and an "all out" attack/Deus Ex Machina (c) There are dev inputs for attacks, like A, B, E, and G. Find the rest of them, if you dare.
This is a test game similar to 1945. Huge thanks to Griffpatch for making the health bar tutorial that I used.
