Nuclear Sub Adventure

You are a member of the skeleton crew which has been assigned to test the sub under emergency conditions. Unfortunately most of the skeleton crew seems to have disappeared (not mentioned in the intro) and so it seems as if you're on your own, running around the sub trying to fix everything that doesn't work, which is EVERYTHING. Lockers and doors won't open, all the radios areeither dead or broken, the generator is knackered so the sub's running off battery (!?) and the nuclear dojamiflip is on the verge of a melt down, very comforting.
