Call of Duty: Modern Warfare 4 is officially leaning hard into its live service model. Following the massive Season 1 launch on November 6, a brand-new limited-time event is now live. Specifically, the Modern Warfare 4 Joint Fire event brings major progression boosts and exclusive unlockable rewards for active players in Season 1.

Modern Warfare 4 Joint Fire Event Rewards & XP Boosts for Squads
The Joint Fire event heavily encourages squad-based gameplay. Consequently, players teaming up will see massive progression multipliers. While you can certainly play the event solo, forming a squad pays off significantly. Squads of two receive a generous 3x progression boost. Furthermore, squads of three or more players will earn a massive 5x boost. Importantly, these multipliers apply universally across standard multiplayer, DMZ, and Warzone. Therefore, players can grind their progression playing exactly how they prefer.
Naturally, this limited-time event offers several special rewards. Players must accumulate Joint Fire XP to unlock nine specific items. These items include XP tokens, Calling Cards, and Weapon Charms. For instance, players unlock the Move on Targets Calling Card at 150,000 Joint Fire XP. Later, reaching a whopping 1,350,000 Joint Fire XP grants a 1 Hour Double Weapon XP Token. Ultimately, claiming all nine base rewards unlocks the grand prize: the Squad Work Hyeon Burst Blueprint.
Wager Matches & Ranked Mode Updates
Meanwhile, the Joint Fire event runs alongside the newly returning Wager Matches. This separate event started earlier this week on November 11 and runs until December 2. Players collect trophies from eliminated enemies or Warzone Supply Crates. Subsequently, they can risk these trophies in Wager Matches or Challenges to earn Apex Attachments and operator skins.
Looking ahead, Infinity Ward confirmed on November 11 that Ranked Mode will finally arrive in Season 2. Raven Software and Treyarch are also collaborating on this competitive mode. While details remain slim, finalists at last weekend’s Monster Invitational already previewed it through the Hijacked mode. However, developers still need to code a tiebreaker, as the preview match awkwardly ended in a tie.
