First off, I'm not sure if this should be in this forum or the Game one, so apologies if this is the wrong place to post.
Anyway, I'm having a surprising amount of fun with Call of Duty: Black Ops 2 - Zombie: Tranzit.
The part I'm enjoying the most, however, is the discovery and problem solving, rather than the survival aspects (though I liked them in the other COD games, and horde modes in general.) I was wondering if anyone could recommend any other titles that fit that sort of, get placed in a world, try to figure things out, almost roguelike mystery game? Preferably multiplayer?
Edit: I mentioned Uru, but misremembered it completely from when I was a kid, and it's not really pertinent to the conversation.
Thanks in advance.
