~A pve mode would be cool, change nothing to game except 2 things: no other players and multiply number of mutants by a large number(when new mutants will be added), and play normally as 100 player battleroyal mode except you fight your way to extraction point fighting mutants only, and blowout storms with a siren to warn the coming blowout(like in stalker games) that will require you to find shelter to prevent radiation damage, and this mode can be played COOP also.

~In middle of the map add chernobyl power plant and give the player 2 options, go to helicopter and escape for a normal reward or try your luck and go to the power plant and fight a mutant boss that will be taken down much harder but end game reward will be bigger.

This is my idea 🙂
