He will return in the ninth season, though.
Requested by the community for months, Activision has finally released a new Zombies mode for Call of Duty: Mobile in season six. Undead Siege mode takes place on Isolated, the battle royale map where players have to defend a mobile base against hordes of zombies.
With so many players enjoying Undead Siege, Activision has extended the limited time mode until the game's ongoing seventh season. On September 10, the developer announced that the mod will leave the game in season eight, but will return in season ninth. The eighth season of the game will begin towards the end of September.
Seasons in CoD: Mobile last about a month, so players will have to wait until at least late October to enjoy the Zombies mode again. Activision has stated that the mode will return with "more" in the ninth season and several updates will be made.
In Undead Siege mode, players had to survive five days and nights. During the day, when the zombies were scattered and outnumbered, players could explore the map for supplies and resources.
These resources can be used to get turrets and other weapons to defend against zombies. As night approaches, zombies begin to appear in waves. Players must work together to defend the mobile base against several waves of zombies. Each subsequent night the zombies get stronger and new ones appear.
