Atomfall is a surprisingly fantastic open world action adventure game, with a heavy emphasis on exploration. The atmospheric breakout hit from Rebellion of Sniper Elite fame takes players into the picturesque Lake District of the northern English countryside. It's the 1950s, and a strange nuclear experiment has led to an entire valley being quarantined off — you're trapped in with the soldiers and locals, all of whom have gone a bit crazy, if they haven't mutated, that is.
