Well, maybe, yes, patrols, recon, any orders that are given out through the navy? I'm only getting started with this, it could take a little time to flesh out, but i believe it could bring some interesting roleplay.
Also, a little more thought for a derelict situation,
Maybe a GLaDOS situation? AI corruption ending in the crew's death?
A million dollars isn't cool. You know what is cool? A basilisk.
