This game I’m looking for is a zombie game, I forgot the name, it’s for mobile.
Game features:
It had a system of passing days.
It was a game where the operations base was on a ship; you could move this ship to various places in the ocean.
The main objective was to exterminate all the zombies in the world.
You had to have good relations with countries to get good weapons.
You could set up military bases in some countries.
You could launch atomic bombs on countries.
You could drive vehicles, and the game was 2D.
