Infinity Ward has released a new update for Call of Duty: Modern Warfare, as well as a playlist update for the game's multiplayer mode on PC, PS4, and Xbox One. While the majority of the patch notes concern various bug fixes, the big news here is of interest to Warzone players, who now have access to the battle royale game's Solo mode.

Prior to this update, the only playlist in Warzone allowed for teams of three to compete against each other (although you could, technically, join a match without any teammates). Now, you'll be able to do battle without having to worry about enemy squads or anything of the sort--you'll win or (more likely) lose based solely on your own actions.
Elsewhere in the update, Modern Warfare's multiplayer has added Cranked Kill Confirmed, Mercenary Moshpit, and 10v10 Atlas Superstory 24/7 playlists. Additionally, alongside the recently added DLC, Gunfight has gotten a St. Patrick's Day theme.

In terms of fixes, Infinity Ward has made good on a recent promise, as kills in Warzone are now credited to the player who downed an enemy. Previously, the player who finished off the downed player was awarded the kill.

You can check out the full patch notes below.
