With Predators only, and not Aliens, they wouldnt last too long either, but they would get scared even more. Think about it:
Your walking along a dark, bashed up corridor. Blood is everywere on the walls. Your taking point, with the rest of your squad five meters behind you. Suddenly your motion tracker goes off You turn around, scared out of you mind, but nothings there. You continue down the corridor. You enter a room, filled with skinned or headless bodies (Security gaurds, as I assume that the Preds follow the code of honour)Your squad members are horrified. Suddenly, your motion tracker goes off again. You dont turn around straight away. You hear a loud, pained scream, and whip around. One of your squad memebers is dead, and being dragged through the corridor you just came from....
BUT, there is a flaw with that. If the predators followed the soce of honour, they wouldnt kill anyone except the security guards, and anything that seemed able to fight it. That would give them little reason to travel there in the first place. However if they were bad bloods, then I could understand them going there.
Come out F@ggerstrom! I know your in there!
