Great use of the theme! The visuals and sparse sound effects create a harrowing experience.
Without exaggeration, I shot hundreds of times, but only got one hit (at least I THINK I did, may have been one of my teammates). And if I tried to get closer for a point blank shot, I would instantly get mowed down. At some point a grenade icon showed up, so I right clicked to throw it, and unfortunately the game froze. So I stopped playing at that point.
It would be a lot less frustrating if 1) the game highlighted the enemy I was shooting at, so I knew the game actually registered my shots, and 2) if there were some sort of XCOM style of percentage hit chances on screen, so I could take calculated risks.
This game is cool, but I felt like my input didn't really matter and I only got past the gates by sheer luck---perhaps intentional from a story perspective, but not fun from a gameplay perspective.
