I'd have to go with an on purpose Fan-Film vibe. We have this secret military place introduced (maybe not secret, but of highsecrecy), no characters are formerly introduced (we see the main characters but the focus is on how the place works), we finally see the main character on screen as a close-up, but just as we see him, Something Happens! (somebody suddenly dies, or something explotes? IDK), there's this huge alert, our main guy (who as would later be introduced as being just transfered to the place) has no idea what's hppening.
Anyway (Sorry for my awful sentence structure) I think it would be interesting for the main guy to meet his companion right when the whole thing is going on and watch them die. As for the purpose of thepredator attack (yep, their predators, something I didn't make clear in the begining) would be for hunt, or maybe there's predator technology or something in the place that they want.
That was completely improvised.
