The verdict

An atmospheric, scary sci-fi tactical shooter with great sound, lighting and AI, but abandoned in Early Access with little content and almost no players. Skip it unless you have friends and a tiny budget.

Great for

Co-op groups of friends who want a spooky, atmospheric tactical shooter for about $10 and accept its limits

Main risk

The game is abandoned since 2019, with very little content and almost no other players online
