As per usual, start up the game and it will prompt you to update to v1.10. The size of the patch is 97 MB, and among other things should incorporate the long-awaited Conquest mode from the older games in the series. Here’s the information from the official site:

A brand new multiplayer mode is here, and it’s free!

Content includes the traditional Battlefield multiplayer game mode, Conquest. Conquest focuses on the capture and control of flags; once a team captures a control point, its members can re-spawn in the area. When a team loses control of all their flags or control points, they cannot re-spawn.

Maintaining control over the flags on the battlefield is a key to victory and the ability to re-spawn troops close to the battlefront can make all the difference for that last offensive push. Four existing maps have been redesigned along with all new lighting and weather effects, to give players a great battlefield on which to play Conquest.  Upon entering one of these maps, the U.S. ARMY will face off against either the Russian or Middle Eastern Coalition forces and the battle for control of the territory will begin.
