You're off duty at your post on the original Death Star when you notice something odd. This is a tongue-and-cheek silly game, I'm not sticking to canon or fanon.
You are a member of the "Special Force" team. For years you've wanted to be a stormtrooper but your disabilities help you back. After years of training and practice you were finally accepted, at which point you were sent to a research facility to help test a new form of armor meant to enhance soldiers. The suits were a failure for most regular soldiers, but proved to be just the right assistive technology for you. Your improved capacities even earned you a spot as a guard on the empires newest weapon, the "Death Star". Seek out vile intruders in your new home with the other members of the special forces team and a sly smuggler. This game will not stick strictly to the official canon, please do not register if you are offended by the idea of disabled stromtroopers being awesome.
