Dark blue-black panels with thin red piping and small printed labels along the receiver. A coiled cable runs down the right side into a round fan grille and a cluster of switches near the rear, and the magazine below is bright blue. The word Jupiter is signed on the lower plate.

The view model runs 5292 polygons on 50 bones, where the stock first-person MAC-10 has 1034. It draws on twenty-six textures, most of them narrow strips for the panelled receiver, plus skin, finger and glove maps at 248×250, 120×126 and 248×123. Player and world models are included at 4692 polygons; the player file still names itself p_tmp.mdl. Animation covers idle, reload, draw and three firing takes, the idle running 307 frames. The archive holds five sounds: shot, draw, bolt pull, magazine in and magazine out.
