Is this a remake of Outpost?
I know Asylum like to copy popular films but there seems to be a lot in the trailer that makes it look like the little British film Outpost.
It kind of makes sense to clone it as the big budget sequel "Outpost II: Black Sun" is due for release and Part III is currently filming.
Here's the trailer for Outpost:
