Fresh from the Tokyo Game Show is the newly announced Left Alive, which will be coming to PlayStation 4 and PC. Toshifumi Nabeshima, director of the Armored Core series, Takayuki Yanase , mech designer for Ghost in the Shell: Arise and Xenoblade Chronicles X, and rather excitingly, Yoji Shinkawa, the character designer for the Metal Gear series have teamed up to create a survival action shooter.
The trailer reveals mechs, which is understandable given the people involved, but also shows a corridor with bullets flying out of doors which seems to indicate human combatants.
