Mod «Slim Bob» for Barotrauma

Slim Bob is a small and compact enough sub to be operated by just one skilful captain! Really lonely captain. You are alone. Only crawling noises behind the walls are keeping you company.
As for actual info - reactor at the front of the sub, airlock with outside motion detector, fabricators for more independent experience, coil gun at the top and discharge coil at the bottom as a reasonable defence and real lack of basic supplies due to space-saving. Be skimpy. Be slim. Slim Bob.
