Call of Duty: World at War Patch is a utility program designed to fix and add new items to the base game of the first-person shooter game Call of Duty: World at War. This patch updates the game to Version 1.6 and installs new maps—three for multiplayer mode (Battery, Breach, and Revolution) and one zombie game mode map, Der Riese, which is set in a secret Nazi research facility featuring the Pack-A-Punch Machine, Teleporters, and tons of zombies. The patch fixes specific bugs, like the favorites list not ignoring filter settings, round count errors, the Friends list online indicator not showing, and joining modded games if you don’t have the mod. If you spend a lot of time playing CoD: World at War and want some more features, this is a must-download.
