New Maps: Dome

Call of Duty: Mobile Season 4 has received just one new multiplayer map, contrary to Season 3 that saw two additions. The new map is called ‘Dome,’ which was first introduced for the previous Call of Duty game Call of Duty: Modern Warfare 3. The map’s in-game location is a military area located in the middle of a desert, which comprises an abandoned military base, a deserted office, and an underground control console. This map will be featured in Multiplayer Modes, including Search & Destroy, Team Deathmatch, and Domination, apart from other undisclosed modes.

New Featured Game Modes

Capture the Gold

Developers bring new featured game modes with new patch updates every time in Call of Duty: Mobile, and this time, ‘Capture the Gold’ has been added as the new Featured mode for MP matches. 

However, this mode is not new to the game, and this update has just marked its return to Call of Duty: Mobile. Capture the Gold will be a time-limited mode that will feature a contest between players to procure gold from the opponents’ base and transport it to the allied base. The mode will be available to play on Crash, Standoff, Raid, and more.
