Call Of Duty: Modern Warfare 3 will feature a multitude of mission-based like Modern Warfare 2 as well as survival Special Ops modes where players will have to keep fighting until they get overrun by increasingly tougher waves of enemies as you progress.

From now until Nov. 8, 2011, Call of Duty fans can enter daily for a chance to enjoy the perks of cash, VIP experiences, vehicles and thousands of other Call of Duty: Modern Warfare 3-inspired prizes.

Fans can pre-order the game at any local GameStop or online and use their receipt or online order confirmation code to enter. The code can be entered once a day for a chance to pick custom perk packs including one Pro perk and two additional perks of their choice. Weekly Pro perks include a 2012 Jeep Wrangler Call of Duty Modern Warfare 3 Special Edition, a trip around the world, Xbox Ultimate Gaming Bunker, Zero-G experience and $10,000 in cold, hard cash. Additionally, customers have a chance to win instant perks each time they enter. GameStop® PowerUp™ Rewards members will also receive double entries each time they participate.

Perk options switch out every Monday at 8:00 a.m. CT with new prize packs available each week. The entry pool resets every 24 hours, so fans can enter once a day during the sweepstakes period. There is a limit of one perk prize per person, family or household.
