S.O.R. -1000 Gamma is security and operations robot, created by the US Army in 2073. He crash landed on the Earth via escape pod Beta. Thanks to the impact, he's feeling a bit discombobulated. He looks pretty much like a typical brain bot, but instead of two arms, he has four; two for maintenance work and two for laser guns (not holding laser pistols, but his additional arms are actually laser guns). He gets around on two tractor treads, similar to the larger security bots.
The Prisoner may find S.O.R.-1000 Gamma in a random encounter treading along erratically, making beeps and whirr sounds. If approached it will wig out and turn hostile. When searched it will have a holodisk containing some information on the B.O.M.B.-001 and its function.
