You play as an escaped bio-weapon codenamed Poseidon in the shooting game Thing Thing. After punching your doctor to death, get his gun and shoot the ceiling of your cubicle to escape. Armed detainers will be after you to get you back to your prison but of course, you'd be gunning them down to taste the sweetness of freedom. Use A and D to move, W to jump, F to change weapons and the mouse to aim and shoot. Enemies with guns have a safe spot around them that you can exploit. You can get into those spots and knock the enemies senseless without losing health.
