Battlefield 3's upcoming Close Quarters map pack, which focuses on indoor combat and is due out this June, won't support the game's "Rush" multiplayer mode, according to a post by lead designer Niklas Fegraeus on The Battlefield Blog: "We understood quickly that Rush, being a large and progressive mode that takes you on a journey from M-COM to M-COM, simply wouldn't fit physically. So instead, we turned our attention to Conquest. How could we tailor this essential Battlefield game mode to fit our new type of environment?"

The result of said tailoring is "Conquest Domination," a new mode inspired by Fegraeus and game designer Gustav Halling's shared nostalgia for Unreal Tournament's Domination mode. "The Domination type gameplay usually takes place on smaller maps, much like the ones we were creating. Inspired by these memories, we used the spawning systems from Battlefield 3 Team Deathmatch and came up with a Conquest mode adapted for smaller spaces."

Fegraeus also stressed flag protection is much more important in Conquest Domination, and that while the differences in the new mode are "subtle," they provide "different tactical layers" when used in conjunction with the new maps.
