This expansion comes with four maps from Battlefield 2 and they are:

• Strike at Karkand
• Wake Island
• Gulf of Oman
• Sharqi Peninsula

On top of the maps, this map pack will be bringing a gob of weapons, a few new vehicles, one additional game mode, and assignments. The weapons are:

As for vehicles, we get one jet (F35B Fighter), one infantry fighting vehicle (BTR-90), and one fast transport vehicle (DPV). The game mode, Conquest Assault, is much like the normal conquest mode we all love and cherish, with one twist. One team will always be defending the capture points, and the other team will always be attacking them. This mode looks to be only available on the "Back to Karkand" maps.

Finally, we have assignments. "Uh... Spratticus, what the hell are assignments?!". Well if you would stop interrupting my blog post, which seems like it would be hard to do... anyway back on track. Assignments are a new way to earn unlocks.  There are ten unlocks and they each have their own list of things you must complete to earn the unlock. The list is below:

• Best Friend Forever (Unlocks FAMAS)
• Fixing It (Unlocks MP5)
• Let It Rain (Unlocks QBB-95)
• Spec Ops (Unlocks QBU-88)
• Familiar Territory (Unlocks PP-19)
• Professional Russian (Unlocks L85)
• It Goes Boom (Unlocks QBZ-97/ Type-97)
• Keep your Head Down (Unlocks MG36)
• Creeping Death (Unlocks L96)
• Scarred Veteran (Unlocks Jackhammer)

For example, the "Let It Rain" assignment requires you to get 20 kills with a light machine gun, and two mortor kills. Overall, they are like quests, complete them, you get a shiny new weapon.  

The content packed into this map pack is huge, especially since the game has only been out for just over a month. Hopefully DICE and EA will keep the future expansion packs this jam-packed.  Most of you may have already seen this (it has been out for a few weeks now) but I though I would throw it on here as well.
