Call of Duty has merged with the post-apocalyptic universe of Fallout, introducing wasteland-themed content to Modern Warfare 3 and Warzone. This limited collaboration features both a premium shop bundle and the time-sensitive Fallout: Vault Dwellers event. Our comprehensive breakdown reveals every attainable reward and the most efficient methods to secure them before the deadline.
The Fallout: Vault Dwellers event remains active through June 26, offering exclusive cosmetics inspired by the iconic franchise. Each cosmetic item is gated behind specific XP thresholds, meaning consistent gameplay across multiplayer, Warzone, and Zombies modes will gradually unlock all available content.
Maximizing your XP gains involves focusing on objective-based game modes, completing daily and weekly challenges, accumulating eliminations, and securing match victories. For optimal results, prioritize small-scale map rotations with high objective density, as these typically yield the most substantial XP returns for both level advancement and event completion.
While entirely optional for participation, the Tracer Pack: Fallout Vault Dweller bundle provides a significant acceleration advantage. Purchasing and equipping any of the four operator skins from this pack grants an additional 2,500 XP bonus per match. Available for 2,800 CoD Points (approximately $24), this bundle includes four distinctive operator skins plus 14 additional cosmetic items.
Below you’ll find the comprehensive list of all event challenges and their corresponding rewards, organized by XP milestone requirements.

At 10,000 XP accumulated, players unlock a distinctive weapon sticker commemorating the crossover.

Reaching 20,500 XP grants a 30-minute double XP token to accelerate further progression.

Demonstrate your allegiance to the New California Republic with this expansive weapon decal, available at 37,200 XP.

Achieving 55,000 XP rewards players with a 45-minute double weapon XP token for specialized armament leveling.

As you progress further, additional premium rewards become available including the Nuka-Cola charm, Battle Pass tier skip, Nuka-Cola Caps sticker, and the coveted “Everyone Disliked That” emblem.




The pinnacle rewards include a double Battle Pass XP token and the exclusive Nuka-Cola Quantum camouflage, representing the ultimate achievements of this collaboration event.


For players seeking to maximize their efficiency, several advanced tactics can significantly reduce the time investment required to collect all rewards. Understanding the underlying XP mechanics is crucial for optimal performance.
Game Mode Selection Strategy: Focus on objective-rich modes like Domination, Hardpoint, and Kill Confirmed within small map playlists. These formats consistently provide the highest XP-per-minute returns when played aggressively.
Time Management Approach: Dedicated players can expect to complete all event milestones within approximately 6-8 hours of focused gameplay. Spreading this across multiple sessions helps maintain performance consistency while avoiding burnout.
Common Pitfalls to Avoid: Many players underestimate the importance of combining multiple XP sources simultaneously. Always activate available double XP tokens during extended play sessions and ensure you’re completing daily challenges alongside regular gameplay.
Advanced Player Tips: Coordinate with squad members to stack objective captures and assist bonuses. For weapon-specific XP, the BF6 Weapons Unlock Guide offers additional strategies that translate well to this event’s progression system.
The strategic principles applied here share similarities with effective approaches in other tactical shooters. For broader gameplay optimization, consult our Battlefield 6 Complete Guide, which covers advanced movement and positioning techniques.
