Aliens: Ultimate Badasses
Thank whatever gods you pray to! Reinforcements have arrived! This is no time to slack off, though. Even though there are more of us, there are still more of them. Our goal is to find out what happened here and get out. No lollygagging and no wandering off. Now get to your assigned patrols.
Aliens: Ultimate Badasses Expansion adds more characters for you to field, as well as Experience cards that add more depth to your Characters. This expansion is not a stand alone game. You need a copy of Aliens: Another Glorious Day In The Corps to use this expansion.
