Shit never goes as planned. After 10,000s of years in space, the damn ship breaks apart in the atmosphere of the new home world. Not only will this probably create an ice age, it also means it is going to be a PITA for the meatbags to run around and gather enough shit to survive.
Oh the mother fucking ship sleeved us in organics.. this shit sucks!
P.S. The little fuzzy things with black rings around their eyes can open cargo canisters. On the bright side, they taste great roasted.
