The Warhammer 40,000: For the Emperor limited-time collaboration brings the grim darkness of the 41st millennium to Modern Warfare 3 and Warzone. This special event, active through March 27, features a progressive reward track where players accumulate experience points to claim exclusive Space Marine-themed cosmetics. Understanding the most effective XP farming techniques can significantly reduce your grind time while ensuring you secure the coveted Righteous Storm weapon blueprint before the event concludes.
For optimal progression, focus on completing daily challenges and objective-based game modes rather than relying solely on eliminations. Our Weapons Unlock Guide provides additional strategies that apply to this event’s progression system. Team-based modes like Domination and Hardpoint typically yield higher consistent XP returns compared to free-for-all matches.

The Know No Fear weapon sticker represents your initial milestone at 9,500 XP. This iconic Space Marine phrase makes an excellent addition to any weapon’s customization options. Early rewards provide immediate gratification while building toward more substantial unlocks.

Reaching 21,500 XP grants the March for Macragge calling card, showcasing your dedication to the Ultramarines chapter. Position this proudly in your player profile to demonstrate your event participation.

The tier skip token at 36,500 XP provides immediate value by advancing your seasonal battle pass progression. This effectively gives you double progression – both event rewards and battle pass tiers simultaneously.

At 55,600 XP, you’ll acquire the Righteous Hatred weapon charm, featuring a detailed chainsword miniature. This particularly complements melee-focused loadouts and adds authentic Warhammer 40K flair to your arsenal.

The Inquisitorial Seal weapon sticker unlocks at 79,500 XP, representing the authority of the Imperial Inquisition. Apply this to your primary weapons to showcase your alignment with the Imperium’s most feared organization.

Earning 109,700 XP rewards you with the For the Emperor emblem, a bold declaration of loyalty to the God-Emperor of Mankind. This mid-tier milestone demonstrates significant commitment to the event’s progression system.

The PSYK-OUT stun grenade cosmetic variant at 147,700 XP transforms standard tactical equipment into thematically appropriate gear. This functional cosmetic maintains gameplay utility while enhancing immersion.

Reaching 195,600 XP unlocks the Sons of Sanguinius calling card, honoring the Blood Angels chapter. This represents the pinnacle of cosmetic rewards before the ultimate weapon blueprint.

The Innocence Proves Nothing emblem at 147,700 XP embodies the paranoid philosophy of the Inquisition, making it particularly appealing for players who enjoy roleplaying darker factions.

The Adeptus Astartes loading screen provides immersive artwork during match transitions, enhancing the overall Warhammer 40K aesthetic experience.

The Double XP token provides temporary acceleration for your progression, particularly valuable when combined with existing XP multipliers from the battle pass system.

Your ultimate prize, the Righteous Storm weapon blueprint, awaits at the highest tier. This fully customized weapon features unique visual elements, attachments, and thematically appropriate aesthetics that truly embody the Space Marine arsenal.
For maximum efficiency, prioritize objective play in medium-length matches. Extremely short matches provide limited XP, while very long sessions offer diminishing returns. Our Complete Guide covers similar progression systems that can inform your strategy here.
Common Pitfall: Many players focus exclusively on eliminations, but completing contracts, capturing objectives, and assisting teammates typically yields 25-40% more XP per minute. Avoid the temptation to play overly aggressively – strategic, objective-focused gameplay generates more consistent rewards.
Advanced players should coordinate with squad members to stack objective completions and challenge progression. The Class Guide offers team composition advice that translates well to this event’s requirements.
