Pin Brawl by Slash & Slash

Pin Brawl is a cooperative, networked-multiplayer, hack and slash game, developed by Slash & Slash. Using WASD keys to move, and the mouse to aim, the player will wander sci-fi urban environments, completing objectives and destroying robotic enemies. Attacking can be done by using attacks tied to the left and right mouse buttons, and by pinballing enemies between players, themselves, and the environment.
