The Sleeper Crew Pamphlet Duo is an officially licensed third-party product for Mothership RPG. With its Extended Cryosleep complications, this pamphlet gives a novel start to any Mothership adventure.
The PCs have "volunteered" to join The Sleeper Crew (a Division of Freezer Operations). Freezer Ops put them in Extended Cryosleep, and leased their cryopods to a Company Client in Rimspace. The Client awakens the PCs only to deal with the worst of scenarios.
The pamphlet includes a character background generator focusing on why they joined the Sleeper Crew, for how long they've been under, how much they know about where they're going, and what they're getting paid for doing this craziness.
Bane/boon tables for the Effects of Extended Cryosleep offer a fun mechanical bent to the adventure to add a little extra madness to the mix.
The two versions are purely flavor: one is written by the Company, the other is written by a Rimwise "volunteer." Just depends if you want this to be player-facing which version you'd like for your game.
