Burger King restaurants are teaming up with Activision’s newest game—Call of Duty: Modern Warfare as well as Grubhub—to bring fans bonus in-game content and experiences.

On October 24, one Burger King restaurant in Los Angeles transformed into a real-life version of the Call of Duty Burger Town restaurant. Within the restaurant, guests found a gaming hub set up by Activision for visitors to play the new Call of Duty: Modern Warfare game. The King of Burgers and the Kings of Call of Duty defended their throne of Burger Town and welcomed guests up for a challenge. Challengers were invited to play Modern Warfare against the King and professional Call of Duty players Scump and FaZe Apex for a chance to win free Whopper sandwiches for 15 years.

For those not in the Los Angeles area, Grubhub is promoting select Burger King restaurants on its app in 16 cities only as “Burger Town presented by Burger King” restaurants. The rebranded “Burger Town” menu will include Call of Duty themed BK Meals with the opportunity to get a code to unlock bonus in game content. The Burger Town menu will be available exclusively via Grubhub delivery. Guests nationwide can also order a Call of Duty themed BK Meal from their local BK restaurant on Grubhub.

To get your Call of Duty: Modern Warfare bonus codes, simply place Grubhub delivery orders from Burger King or “Burger Town” locations and use code ‘BKCALLOFDUTY’ at checkout. For the first qualifying delivery purchase, guests will receive a code to unlock a bonus in-game “Burger Town Emblem.” On the second delivery purchase, guests will receive a code to unlock a “Burger Town Calling Card.” On the third delivery purchase, guests will receive a code to unlock the “Burger Town Bubby Weapon Charm.” From 10/24 through 11/6, Grubhub diners will also qualify for free delivery on an order over $10 from BK and “Burger Town” locations (no promo code needed). To order, download Grubhub on on iOS or Android phones.
