Naked Risk 3D [v1.2.3] By Brazen Games ((NEW))
A suggestion: Some kind of visual indicator of people who are nearby but offscreen, and another indicator of anything that's increasing your risk. Hopefully when the stealth system is tied more to NPCs seeing you- it would feel appropriate to be able to make a mad dash away from someone, but the sound of you running attracts people. Have you played Assassin's Creed? The NPC-based stealth in those games is really good, perhaps you could get some ideas from it.
