Call of Duty: Advanced Warfare is the next installment to a series of great shooters. Overall I've enjoyed all of the COD games that I've played and I believe it will be the same for Advanced Warfare. You'll get the Exo-Survival coop mode, new weapons, abilities and more.
In addition to that, for the 24 hour early access, You get two custom in-game weapons (AK-12G assault rifle and Crossbow-B2), a full day of double xp on November 3rd and Advanced Arsenal which includes a custom EXO and EM1 weapon. The Season Pass is also available and will run you $49.99 which grants you access to the Atlas Gorge Bonus MP map (COD's Pipeline) and more.
