The art and sound design in this are great (Though the mix is a little weird, some of the sfx like the rock fall were way loader, but that's a minor thing). I really liked the aesthetic of the world, the varied heights and textures of the walls and surfaces and the creepy monsters. A fun place to explore, and one my favorite looking games I've played so far.
The game-play was good, movement felt snappy and responsive and the combat was pretty juicy. I actually died the first time, because I'd burned my stim way to early, but once I varied my approach I made it to the captain and didn't have any more issues. I never used the radio.
Strong narrative as well, and a really cool approach to the cutscenes.
Really strong entry, I enjoyed it a lot.
