A rotary multi-barrel gun replaces the submachine gun. The barrel cluster is black and clamped in a grey steel yoke; behind it sits a cylindrical black housing with a small printed warning label and a lifting ring on the side. A belt of brass cartridges feeds in from the right and hangs loose over the receiver. The hand on the forward grip is bare, with a black sleeve behind it.

The first-person model runs 1888 polygons against 1248 in the stock P90 view model, on six textures: three large 512 sheets for the body and barrels, one 256×128, and small separate maps for the hand and thumb. Player and world models are 313 polygons on a single 256×256 sheet. The skeleton is unusually thin at two bones, and the animations are long: 30 frames of idle, 166 of reload, 61 of draw and 45 for each of the three firing takes. Two sounds ship with it, the shot and the magazine release.
