Epic Games has released the free Haven downloadable content for Gears of War: Judgment, which adds the Execution multiplayer mode and a single map, Haven.
Execution is a team-based deathmatch where players can only been killed with a one-shot kill. If they aren't, they merely are stunned for a bit.
To celebrate the release, Haven and Execution playlists have 200% XP for the next few days.
The DLC is available from the Xbox Live Dashboard and Xbox.com.
