This games keeps getting better and better each new major update.
Recent update adds a new map, new weapons, a new faction, story missions featuring the voice of Jane Perry (!!)

1.3 is a huge milestone for this game, it has some rough edges like every early access, and keep in mind this is an Alpha, yet devs work very transparently [seriously, check out their discord] and do everything they can to fix the immediate issues. Despite that I've been able to spend 300+ hours in this game across all versions, having non-stop fun in both co-op and in singleplayer, and more than 20 with the recent update.
The new AI is spot on, you can tailor it to your liking and if you know who Solarint is, you know that this can improve significantly overtime. He's the new dev in charge of the AI.

Can't recommend this game enough if you are just looking for a chill, but similarly punishing to other extraction shooters experience.
