Coherent Beam has you, the protagonist, saving the world in an alien landscape. Use the Q, W, A, S, D, and E buttons. A and D move you left and right while W lets you jump and S is the crouch button. Toggle between weapons with Q and E. Clicking the mouse will have you shooting your weapon. You'll need to avoid enemy fire by crouching and jumping as you fire your gun. Watch your health meter! You'll pick up new weapons along the way and every level offers more action and a new background scene along with harder enemies. Coherent Beam will also save as you complete missions.
