The game of 'The Thing' was the most famous one to implement a sanity/paranoia mechanic. I imagine this was just inspired by the RPG mechanic, most likely.
Some nice moody visuals, but aside from slowing down time (which I'm assuming has limited uses), I'm calling this what it is: The description sounds like a rip of 'Space Hulk', right down to these "rogue commandos" basically being reskins of Chaos/Nurgle Space Marine encounters. Games Workshop's notoriously litigious legal department might be watching closely.
Except that game's most recent incarnation at least had a play-as-Tyranids mode. Without one for the Aliens, this could well suffer from being a bit too same-y.
The actual visuals and lighting strongly reminded me of the recent remake of the 'Alien Breed' games. Wonder if it could be the same engine.
