"Call of Duty: Modern Warfare" Season 4 has been released and includes a major 45 GB update; Modern Warfare is once again hosting a free weekend, accessible via Warzone.

This free weekend runs from today through June 15, but it does not offer full access to Modern Warfare's multiplayer. Instead, you can check out the Gunfight playlist, which includes five multiplayer maps, including the new 6-on-6 Zhokov Scrapyard and Hardhat maps, and seven new maps, including Trench, where you can play in teams of three.

The Gunfight playlist will keep you pretty busy through next week, as it is considerably more extensive than the previous free weekend, when you could only play on five multiplayer maps.

Season 4 main edition features three new maps, Captain Price added as an operator, and new assault rifles and SMGs; Warzone has also been updated, adding a 50vs50 mode and a Contraband contract. Two more operators, another new map, three new modes, new weapons, and plenty more to come in Warzone.

If you have Warzone installed, you can check out the Modern Warfare multiplayer and Gunfight playlists starting today at 6 pm (10 am CST). If you don't have it installed, you may want to sort it out now, as it will take a while to download.
