Map Pack 3 for Call of Duty: World at War is a downloadable content pack that was released alongside the Call of Duty: World at War Patch version 1.6. The patch contains some minor bug fixes and a few enhancements to improve overall gameplay. The other part of this download is the Map Pack. Installing the patch/map pack 3 will unlock three new competitive multiplayer maps: Battery, Breach, and Revolution. In addition to these competitive multiplayer maps, there is also a new Zombies! multiplayer map that expands the Zombies game. This map takes place in a top-secret Nazi research facility called Der Riese, and is the largest Zombies map to date.
The Call of Duty World at War Map Pack 3 and Patch v1.6 are available to download for free via the download link below. However, if you installed the digital version of the game via a digital distribution service such as Steam, patches will be applied automatically, and any recent copy of the game, digital or physical, should already have the patch applied. The information below details everything that was included with this release from Activision and Treyarch.
Downloading Call of Duty Map Pack 3 and Patch v 1.6 is not necessary for the reasons stated above, but if you're playing with an older physical CD/DVD copy of the game you may find the download link below useful.
Call of Duty World at War is the latest game in the "Call of Duty" series set during World War II. There have been rumors that an upcoming "Call of Duty" game could return to the theme, but it's been over eight years since that release and there doesn't seem to be much of a delay in the modern and near-future storylines told in the Black Ops saga or the newer Ghosts and Advanced Warfare stories.
