Extremely barebones. The first level was pretty cool, but the second you die it immediately feels repetitive. Very little content, feels like an indie game.
You need steam friends who have this game, as there's no matchmaking. Additionally, you can't play solo, I've tried several times and it's impossible. I couldn't even get past the first alarm door. Definitely not worth anywhere near 30 bucks, and I assume playing with friends wouldn't carry that same scary vibe they're going for, and for reference, it's about as scary as left 4 dead, which is cool the first time you boot it up, but quickly becomes very basic.
