Journey to Planet 326

I woke up alone, around me the dead bodies of a dozen men and women in white coats lay scattered about the Labratory. I couldn't remember my name, how old i was, or why i was there, but i figured leaving would be my best chance. Outside was worse than inside, outside there was no one at all, it was as if someone had come killed everyone, then took their bodies to a mass grave somewhere on another planet.
I supposed I survived for a reason, granted that reason was only because i wasn't human, not fully anyways. it seems I was part robot, One of my legs was metal, the bottom half of it, and my right arm was too, each attached to nerves so my brain controlled it like their flesh and bone counterparts.
As if life couldn't be worse, now I've got a half dozen guys dressed in hazmat suits following me around until they can figure out how to get home.
