Call of Duty released it's brand new Battle Royale game mode called Warzone. It's free to play for everyone on all consoles and it's also cross-platform compatible which means you can play with your friend even though they are not on the same platform you're on.
Warzone has all of the guns and mechanics of Call of Duty Modern Warfare but with up to 150 players in the lobby trying to be the last man standing.
One of the features added into this Battle Royale that is different from the others is the ability to respawn directly after death by winning a 1v1 match in the "Gulag". Once you've gone to the Gulag you have no more chances to fight your way back into the game. Luckily if you have a teammate they can collect money throughout the game to "buy" you back. In addition to this, there is also mini-challenges you can do in-game to earn money and other perks. These challenges include a bounty that puts a bounty on a nearby enemy, and upon their death you earn money, Recon allows you to see the next safe zone, and Scavenger gives you money and a gas mask.
There are also vehicles all over the map that you can use to either get you to your next safe zone or to even eliminate other opponents.
