As a lead-in to a Rogue Trader campaign I'm planning on having the players acquire their starship. Looking at the "past histories" and seeing "wrested from a space hulk" I thought a dungeon crawl through what will become their ship seemed like a cool idea. The primary objectives will be to power up the ship (restore the plasma engine) and restore command and control (connections to the bridge). In 40k tradition there will be some genestealers and other tyrannids hybernating on board.
My question for the forum is, what are some other obsticles I could put in this type of adventure? I'm kinda coming up blank on thinking of other interesting challenges to overcome. Maybe some puzzle-like challenges or non-combat skill related challenges, since the Tyrannids will have combat covered?
Thanks for any input!
