Mini-bot 528

this enemy is a small robot about 2x as tall as a dwarf bulborb, and fires electron beams at your squad every 10 seconds. it has a small weak-point on it's back, so use one captain as a distraction, the other attacks the screw on it's back. it moves slowly, so use that to your advantage. it looks like 2 small, square metal boxes screwed together and with treads on the bottom.
