DICE has released a new trailer premiering the next expansion pack for the action packed FPS Battlefield 3, with hints at a crossbow weapon, earthquakes and a new game mode. Aftermath will also include four new maps, as well as new weapons and vehicles.

This trailer provides a premiere look at our fourth multiplayer expansion pack Battlefield 3: Aftermath, where we throw players into an all-new harrowing environment: The shattered districts, streets and cities of post-earthquake Iran. Players will struggle for supremacy and survival amongst the devastation, with heavily modified vehicles and the all-new crossbow at their disposal.

Battlefield 3: Aftermath features all multiplayer game modes from the base game, plus the all-new Scavenger mode. In Scavenger mode, lost soldiers start equipped with only a knife, one grenade, and sidearm and must search the environment for more powerful weapons to increase their chance at surviving and eventually winning.

The new mode hasn't been classified yet as being a team based mode or simply a free-for-all deathmatch so keep an eye out on that.
