I did find it odd that we didn't get a variation on the classic Aliens colony at any point in the game. As it stands, we have locations that are based on Alien and the two prequels, but none from the movie it actually takes its title from (unless you count the Endeavor). Hopefully a Pala station campaign would address that, and I'm all for some areas that are based on the look of the refinery in Alien 3 as well. Some parts of the Katanga replicate the style of Alien 3 and Resurrection, to an extent, particularly in 1-3.
