Batman: Arkham Origins (October 25h, 360, PS3, PC, Wii U) + Handheld versions

[Smeags]

Added video to OP. ^_^

Some interesting story bits:

Takes place in the actual Gotham City on Christmas Eve.
10 Assassin's have come to Gotham for the sole reason to kill Batman (guessing this includes Deathstroke from that GI Cover).
