Fallout 3 Grey Sky

Grey Sky is an open world shooter inspired by GSC Gameworld's S.T.A.L.K.E.R. Shadow of Chernobyl. You explore the abandoned town of Clear Fortune, as you attempt to avoid the military presence there, figure out what caused the strange explosion in the center of town one year ago, and most of all, survive. Grey Sky implements many new gameplay features original to Fallout 3, including a new system of bleeding damage, a need to eat and sleep, an immersive HUDless health display, bizarre spatial anomalies, and a Commentary Mode system like the one found in Valve's The Orange Box.
