It WAS playable so I'm forced to Approve it. However. . .
The terrain was rather simple, and all the rocks on the sides were "floating" which was very unnerving and unnatural.
The cameras were very simple and oftentimes would cut through the ground. =P
Triggers were rather simple too and many times things wouldn't happen quite as I think they were planned(i.e. the Captain says "we got to get some cover" but everyone else is already dead, The catapults continue to fire at the ground [no one is there] and other things like that.)
