The atmosphere setup is really cool. The lightning, the spore effects on the floor, the creepy radios, it all builds this really uncomfortable vibe. And that death scream? Yeah that made me jump at first lol. Also, are the voice lines recorded for this?
I like the loop of diving in for 90secs, grabbing what you can, then coming back to buy upgrades. It makes each fun feel tense. It is tough-tough though, on my second day I walked out and immediately got jumped by the same group that was camping the door from the previous run.
Still, the game is super immersive and memorable. I had a good time with it.
