I remember way back in January, I suspected an underwater scene would appear in AvP2. Alien Experience is now reporting that it will be a big action sequence:
“The scene is just mentioned in a passing glance as one of the films shot in the Vancouver area that features underwater filming, but I’ve asked around and it seems it all boils down to one scene that features some mayham, carnage, and of course, people dying.” says Hicks.
I loved the scene in Alien Resurrection though and I wouldn’t mind seeing the aliens back underwater again. Let’s hope it’s a great sequence. Thanks to Darkoo for the news.
Now seriously, comics and movies don't mix... the canon for Alien and Predator is movies, not the comicbook, though Paul Anderson adapted a few aspects of the comics to the silver screen... But the breathing stuff in space is still non-canon, otherwise...The Queen might still be alive...!!! Oh no!!! We can do an Alien5 after all !!! 
Swimming is actually one of the most easiest things for animals (at least, those who are physically capable of doing so), because we technically 'grew up' in the liquid environment of a womb or egg. Just look at baby crocodiles, ducks or sea turtles (all air-breathing creatures and lacking gills). They don't have to be taught, they just race to the nearest water and do it! 
Let's all hope yo!
jesus christ not another under water scene! thats all we need! Alien Rez repo or what!
