Joint Fire rewards XP earned while playing in a party. The multiplier depends on squad size:
The event works across Multiplayer, DMZ, and Warzone. Players need 1,350,000 Joint Fire XP to complete all nine milestones and unlock the Squad Work Hyeon Burst Blueprint.
| XP Requirement | Reward |
|---|---|
| 150,000 | Move on Targets Calling Card |
| 300,000 | 30-Minute Double Weapon XP |

| 1,200,000 | 30-Minute Double Battle Pass XP |
| 1,350,000 | 1-Hour Double Weapon XP |
Completing the track provides 2.5 hours of Double XP, 1.5 hours of Double Weapon XP, and 30 minutes of Double Battle Pass XP.
Best approach: Play with at least three players to maximize the 5x multiplier. Daily Challenges also provide additional XP and reset at 12 AM PT.
Wager Match runs from November 11 to December 2. Players earn Trophies through eliminations in different modes, with additional Trophy opportunities from Warzone Supply Crates.
The Gauntlet playlist introduces 1v1 Gunfight, where the winner stays to face the next opponent. DMZ and Warzone also have dedicated Wager Challenges.
Key rewards include:
| Requirement | Reward |

| 1,000 Trophies | Venom Pile Camo |
| 10 Event Rewards | Kastov 545 Apex Attachment |
| 15 Event Rewards | Vitriol Operator Skin |
The ten cheapest rewards cost 435 Trophies in total. The November 13 update also increased Trophy drop rates in Multiplayer and DMZ.
Players targeting weapon upgrades should prioritize the ten-reward milestone. Six additional rewards will be revealed on November 18.
The latest weapon update reduces flinch and extends damage ranges across several weapon classes.

|---|---|---|
| Assault Rifles | -25.4% | -7.8% |
| LMGs | -19.3% | -13.3% |

| Cronen Squall | Mid-range: 37.34m → 43.18m |
| Kastov 762 | Maximum range: 26.67m → 28.7m |
| Oden | Mid-range: 50.04m → 58.42m |
| HAN 86 | Maximum range: 30.48m → 32m |
| Axion | Mid-range: 38.61m → 40.13m |
The M4 receives a 26% increase in maximum damage range, making it one of the most noticeable AR changes.
| Weapon | Main Changes |
|---|---|
| Wz.55 Striga | Maximum range: 11.94m → 14.61m; mid-range: 21.34m → 28.7m |
| PPSh-41 | Maximum range: 10.8m → 13.34m; minimum damage: 13 → 14 |
| ISO Nightshade | Mid-range: 20.45m → 22.99m; minimum damage: 14 → 16 |
| CSG-35 | Minimum damage: 13 → 14 |
| X-58 Nyx | Maximum range: 10.8m → 11.94m |
The Wz.55 Striga receives the largest listed SMG range increase, while the PPSh-41 and ISO Nightshade gain more consistent minimum damage.
Aim assist is now disabled when shooting through smoke from Smoke Grenades or the Smoke Wall Field Upgrade. This also applies to gaps created by gunfire and explosions.
Controller players must rely more on manual tracking when engaging enemies through smoke. Use smoke for repositioning, crossing exposed areas, and breaking enemy sightlines rather than relying on assisted targeting.
The November 13 update addresses several DMZ progression issues:
In Resupply Run, collect requested items from points of interest and deliver them to the Events station for equipment such as Self Revives and 3-Plate Carriers.
Check the requested materials before selling your inventory. Prioritize nearby collection points and complete several objectives in one deployment to reduce unnecessary trips.
The Emerald Reaper Starter Pack became available on November 13.
It includes:
The bundle is reactive. Purchases made through console or Steam stores are not cross-platform.
The November Season 1 updates provide several useful progression opportunities. Joint Fire offers the fastest event XP multiplier for full squads, Wager Match rewards players with weapon attachments, and the Double XP weekend helps accelerate weapon leveling.
The M4, Wz.55 Striga, PPSh-41, and FiNN LMG Adverse Apex are among the weapons worth testing after the latest balance changes. DMZ players can also benefit from the improved Resupply Run system and corrected X01 item conversions.
Combining event progression, weapon leveling, and resource collection is an efficient way to advance through Season 1. Many players lack the extra time to level up in-game due to work, studies, or other commitments. MW4 Bot Lobbies and boosting services offer an excellent solution, helping players overcome challenges so they can truly enjoy the game. What are you waiting for?!
