Well, despite the fact that nobody has responded to my last post for several weeks now, I have made up a list of EU material that I'm going to make questions for in the giveaway. They should all be fairly easy to get your hands on at a library if you don't already have them, except for the games. You'll have to ask other AvPGalaxy members about them.
Aliens Colonial Marines
Aliens vs Predator Deadliest of the Species
Aliens DNA War
Aliens Omnibus 1
Aliens vs Predator 1
Predators Prequel (can be found in the Predators TPB)
Predators Sequel (can be found in the Predators TPB)
Aliens vs Predator Classic 2000
Aliens vs Predator 2 Gold Edition
Aliens vs Predator Prey
Predator Concrete Jungle (book, not game)
I may add more later on, but this is the list so far. So now you know what to look at for the giveaway.
