Battlefield 1943 will release this summer as a $15 downloadable game from Electronic Arts. It will consist of three maps from Battlefield 1942, rebuilt from a newer engine, with support for 24 players online.

However, Electronic Arts announced a fourth map waiting in the wings that you can't have until you and everyone else has laid some groundwork.

The WWII Coral Sea map will be unlocked when the multiplayer community achieves 43M kills on Xbox Live and the same number on PlayStation(R)Network.

I'm going to guess it'll take the Playstation 3 considerably longer to reach 43 million kills. Also, before you get too excited about a new map, Coral Sea is for airplanes only. Flight sim lite, anyone?
