Call of Duty is on the mobile devices now. You can download from both Apple and Play store.
There is no campaign, just online matches against real players. There is Nuketown and other maps you will recognise. There is TDM, Frontline, S&D, Domination and sort of PUBG type mod.
Once you reach level 5 you can join clan. Look for RebelsOfCarnage (one word).
It looks really sick.
