GURPS: Fallout – Vault 26

In the grimdark future where war, war never changes, some people built a Vault in the Ozarks. Other people survived the nuclear war by hiding in the vault. Today, the door to the vault opens. What will the citizens of Vault 26 do in the post-apocalyptic Ozarks? Can they become a powerful faction like Beartown or Neo-Branson or will they fall prey to the raiders or giant ants that plague the region? This is a 2 session game. We never played another session, but that's no reason to deprive you of it. We used GURPS 4th edition, some online Fallout GURPS material, and the GURPS mass combat rules.
