No your eyes aren't fooling you, this isn't a fantasy mod twist on an Assassin's Creed game. What you're looking at is gameplay from the upcoming Styx: Master of Shadows in this latest trailer from developer Cyanide Studios. For just over three minutes watch this mischievous green assassin make short work of his enemies utilizing both environment and general skill to do so. Styx is slated to release this October on the PC, Playstation 4, and Xbox One. Just in time for Halloween, fitting for a game with goblin assassins don't you think?
