Ran this one recently. Really fun little scenario. I have one group who like to play 3 to 4 hour standalone games and this works perfectly. You could make anything from a 2 to 6 hour scenario on this I think. Or you could just have it as a location in passing in a bigger campaign.
I didn't use the timeline and only used a couple of the animals for my session. That was tough enough. I set up a scenario where the disgraced CEO had somehow managed to upload his consciousness to the ship AI and was holding the other CEOs as unconscious hostages until the company revives him and put him in sole control of the corporation. The PCs are allowed onto the ship as the AI attempts to recruit them into its cause. They're just there to scavenge. But the hostage situation is the only thing keeping the escort ships at a distance! I put little puzzles or challenges on the cryo tombs as well, that need to be passed to open them. That seemed to make a pretty challenging 4 hour session. Feel free to steal or remix that if you're reading this.
Underrated!
