A small square arena with a pit surrounded by a ledge, four pillars, and four rooms. Vacubobs and devlins will duke it out in the pit... you can watch, or you can jump in for the nuke guns.

A small mazelike map, with an embedded physics model that keeps you on your toes. (It's designed to be played solo-the SPN stands for SIngle Player Network.) You get one magnum (and, if you kill the infrequent vacubob, a fusion pistol), and your job is to kill as many bobs as you can. (There is no end.) Good for target practice... the bodies really pile up. Enough recharge canisters appear that you can keep going as long as you want to.
