Subrenity: a firefly class cargo submarine

It must have been so long since this Firefly class ship saw any usage, she's no longer space worthy but she'll do for a submarine, sinking's what she's good at. Your grandparents used to fly on one of these but you never thought you'd see one, gotta wonder if it's the same one, hopefully all the guns you bolted on and waterproofing you did holds up enough to get to the core alive.

• Panel selectable coilgun and depth charge, depth charge can be loaded with rail shells

• Nose discharge shocker electrical sneeze device.

• Auto reactor controls with emergency soft shutdown from nav and a big red panic button.

• Oxygen management system, only run the O2 generator when you need it.

• Power saving Oxygen refill, hit the button on the dive suit area to recharge for 2 minutes, hit it again to stop.

• Floodable airlocks for artifact storage.

• Mineral scanners with front panel power switches.

• Spacious Cargo area.

• A really bad armory full of exactly one TV show reference joke.

• Lots of light switches so you can go submarine-dad mode and get angry at people for not turning off lights after they leave the room.

• Upper airlock combination lockout, default combination '1234', can be edited by changing the memory below the captains chair.
