The 'Power Changes Everything' trailer for Call of Duty: Advanced Warfare throws in some heavy mech units that reiterates the game's frequent comparisons to Titanfall.

This Advanced Warfare trailer is filled with action and introduces us to its new four-player co-op mode, Exo Survival. Based on the trailer, Exo Survival is essentially the Horde Mode from the likes of Gears of War where you must bunker down and try to survive wave after wave of enemies, with each offensive being more intense than the last. Fighting off hundreds of combat drones seems intense. Sure, the heavy mechs are nowhere as big as the Titans from Titanfall, but given all of Advanced Warfare's new maneuverability, futuristic weaponry and the cockpit layout of the mech, the comparisons to Respawn Entertainment's debut title are even stronger than before.

It doesn't help that Respawn is headed by Jason West, who directed Call of Duty: Modern Warfare 1 and 2, the two games that put the franchise on the map in the first place. Nevertheless, Advanced Warfare is a much-needed breath of fresh air into the COD franchise.

Pre-ordering Call of Duty: Advanced Warfare will get you a copy of its Day Zero Edition, which gives you full access to the game on Nov. 3, a day before the official release, along with Double EXP. Advanced Warfare officially launches on Nov. 4 for PlayStation 4, Xbox One, PC, PlayStation 3 and Xbox 360.
