Encased. Had it for a long while, but it’s an abandoned effort of a defunct company aka the money ran out towards the end of development, so they rushed for an early release, but failed to stay afloat. Anyway…

An isometric RPG where you’re the new employee arriving on an extraterrestrial rendition of the Zone. And it’s called the Dome! Welcome, Stalker!
You got character creation with attributes, skills and perks, you got flinging bolts into anomalies and you got the monolith with zombie stalkers running around hearing voices. What’s not to love?
Probably the end game. But I wouldn’t know since I didn’t get that far yet.

Also, the narrator’s voice is that default early LLM voice YouTubers are using for their short alien stories. So, geh.
