Back to Karkand was available to everyone who pre-ordered Battlefield 3, but has since been available for purchase for anyone who wants extra maps and weapons. Speaking of which, here is what you get in the Back to Karkand DLC pack.
• Four reimagined Battlefield maps
• 10 weapons and 3 vehicles
• Conquest Assault mode
Conquest Assault mode is back from Battlefield 2 and plays similar to a game of Conquest with a little bit of a twist. One team starts with all map flags captured and it’s up to the attacking team to gain control before their tickets whittle down to nothing.
• Additional dog tags
Back to Karkand brings back four classic maps from the previous Battlefield games. These aren’t just quick reskins; each one is completely remade for the modern era, making them feel almost entirely new.
• Strike At Karkand
• Wake Island
• Gulf of Oman
• Sharqi Peninsula
• F35B - fighter jet
• BTR-90 - infantry fighting vehicle
• DPV Jeep - fast transport vehicle
