Season four will be the next big update to Call of Duty: Warzone which will offer a lot of new, new maps and new game modes.
Maybe not really new maps but real classics will return as I think many will recognize if you played Call of Duty in recent years, including Hijacked 6v6 comes to Call of Duty: Warzone which was my personal favorite once upon a time.
There will also be a new game mode called Payload where you play in two different teams, 20 players per team. The goal is for one team to escort vehicles with, among other things, satellite parts and all this must be done before time runs out, the other team will, as you may have figured out, try to stop them, in virtually any way, as long as they are stopped.
Warzone gets a new kill streak which is Sentry Gun, it also comes with two new weapons which are OT9 (SMG) and a nail club.
Season 4 of Call of Duty: Warzone will be released on July 15 and the update will be available at 06.00, the size of the update will be around 9GB.
