Complete All Season 2 Week 4 Challenges in Black Ops 7, Warzone

1. Weekly challenge structure and what it means for you

Each core Call of Duty mode — Multiplayer, Zombies, Co-Op & Endgame, and Warzone — features six weekly challenges, producing 24 total tasks every week. As Dot Esports notes, “Every task counts toward unlocking the Season 2 animated camos and rewards some sweet XP,” so every challenge you finish pulls double duty for cosmetics and progression.

3. Weekly refresh and persistence

Weekly challenges refresh on a predictable cadence — “weekly challenges refresh every Thursday at 11am CT / 9am PT / 12pm ET / 5pm GMT.” Dot Esports also makes the player-friendly point that “The challenges remain until Season 2 wraps up, so they don’t expire at the end of each week,” meaning you can batch tasks across sessions instead of racing a one-week timer.

4. In Endgame: Clear a Toxin Field or Toxin Source 5 times — 5,000 XP

This high-value Endgame task is worth 5,000 XP and directs you to toxic map objectives. Dot Esports’ step-by-step tip: “Find the marked toxic buildings on the map, hack your way inside, eliminate all glowing spores, and take down the Elite enemy that appears.” That quoted sequence is the clearest route to efficient clears — focus on the marked structures and be ready for the Elite spawn.

5. Destroy 25 Guild Drones, Sentry Turrets, or VTOLs — 3,500 XP

Worth 3,500 XP, this is a quantity objective that rewards targeted engagements rather than long fights. Dot Esports suggests a reliable method: “Pick up a Surveillance Control contract in a Tier 1 zone, damage the main drone to spawn smaller ones, then destroy the small drones while keeping the main drone.” Use contracts that funnel drones and concentrate on the smaller spawns to rack up numbers fast.

6. Eliminate 10 Special Enemies — 2,500 XP

This Endgame elimination task awards 2,500 XP and requires hunting the game’s named or elite NPCs rather than standard mobs. It’s an ideal candidate to pair with other Endgame objectives since Special Enemies often appear around Mystery Cargo, Toxin Fields, or Strongboxes — remember that challenges don’t expire, so you can stack this with other Endgame runs.

7. In Endgame: Complete the Mystery Cargo Assignment 15 times — 5,000 XP

At 5,000 XP, this is another top-tier Endgame task focused on the assigned blue-marked container missions. Dot Esports’ exact guidance is: “Head to the blue-marked Mystery Cargo missions on your map, reach the container, defeat the special enemy that spawns, and grab the loot.” Repeating Mystery Cargo is straightforward if you concentrate on zones where those assignments spawn repeatedly.

8. In Endgame: Loot Supply Caches or crack Strongboxes 10 times — 3,500 XP

This 3,500 XP task rewards straightforward looting actions in Endgame runs — open caches or crack strongboxes until you hit ten. Because looting is often done while moving between objectives, this is a good filler task to combine with higher-intensity objectives like Mystery Cargo or Toxin Field clears.

9. Get 10 Kills with the D.A.W.G. Scorestreak — 2,500 XP

A 2,500 XP scorestreak challenge that asks you to secure 10 kills with the D.A.W.G., making it a fit for objective-focused Endgame rounds where scorestreaks can be used repeatedly. Treat this as a modular task: if you’re already using D.A.W.G. for area control or clearing AI, track kills each run until the count finishes.

10. Pick the fastest route to the Week 4 Arc reward and XP math

If you want the Week 4 attachment fast, Sportskeeda’s recommended approach is the one most players should use: “The best tactic is to go through the list first, select the six tasks that you feel are the easiest, and complete them to quickly unlock this reward.” Completing all 24 tasks is optional but lucrative — Sportskeeda states: “If you manage to complete all 24 tasks, you will receive 98,000 XP.” Combine easy picks with high-XP tasks where possible to maximize progress per session.

11. Week 4 reward naming and what it does

The Week 4 unlockable is an Arc/ARC-branded M1 attachment; Dot Esports lists it as the “ARC M1 Assault Frame underbarrel attachment” while Sportskeeda spells it “A.R.C. M1 Assault Frame attachment” and Windows Central refers to it as an “Arc M1 launcher attachment.” Windows Central adds a gameplay read: the attachment “improves charge time and cooldown, and might actually be worth having if you're choosing to use the Arc as a weapon towards any of the Mastery Camos.” It’s notable because the Arc family is called “one of the most annoying weapons in the game to use,” so this attachment’s QoL benefits are meaningful if you’re chasing weapon mastery.

12. Multiplayer, Zombies, and Warzone Week 4: structure and available examples

Every other mode — Multiplayer, Zombies, and Warzone — also includes six Week 4 tasks, but the supplied excerpts only include the Co-Op/Endgame list in full. Sportskeeda and Dot Esports both confirm the 6-per-mode rule (24 total). For context on typical challenge wording and XP tiers, Game8’s examples from prior weekly challenge formats show familiar patterns: high-value tasks at 5,000 XP, mid-tier at 3,500 XP, and small tasks at 2,500 XP (examples include “Get 250 Eliminations with LMGs. — 5,000 XP” and “Get 25 Eliminations with Secondary Weapons. — 2,500 XP”), demonstrating how you can prioritize which tasks to pick when mixing modes.

13. Endgame completion tactics you can rely on

Use Dot Esports’ specific how-to steps for Endgame objectives to cut time: target marked toxic buildings for Toxin Fields, pick up Surveillance Control contracts to force drone spawns for the drone/turret task, and head straight to blue-marked Mystery Cargo nodes to finish repeated assignments. Remember Dot Esports’ scheduling tip: “In fact, it can work in your favor, since you might be able to knock out multiple challenges at the same time,” so plan runs that tick off two or three Endgame tasks per run.

14. What else is live this week and final takeaway

Beyond Week 4 challenges, Windows Central notes concurrent BO7 content you can play — the Lunar New Year LTM “Luck Confirmed,” which offers the Mane Character emblem as an exclusive reward, a winter refresh of Rebirth Island in Warzone, and other seasonal items like the Incandescence Mastery Camo and a Classified placeholder for unclaimed Dark Ops Challenges. Bottom line: pick the six easiest tasks across the 24, lean on the Dot Esports how-to steps for Endgame objectives, and you’ll unlock the ARC/Arc M1 Assault Frame attachment while stacking progress toward Season 2 animated camos and up to 98,000 XP if you go all-in.
