Call of Duty: Black Ops 7 gates its hardest mastery camo behind a full round of weapon-class challenges spread across Endgame, Multiplayer, Zombies, and Warzone, and clearing every task unlocks Dark Matter. Which challenges take the longest, and where should players actually farm them? This guide covers the trickier requirements for Assault Rifles, SMGs, Shotguns, LMGs, Marksman Rifles, Snipers, Pistols, Launchers, and Melee weapons in each mode, based on tested methods rather than guesswork. It's aimed at players chasing the full Dark Matter set who want a faster route through the grind, whether they play Endgame regularly or only for these challenges.


Endgame Farm Spots

Guild Tech Kills Cluster Together

The Car Factory and Old Arsenal are tier one zones where Guild Tech robot enemies frequently spawn five or six at once, making the 75-kill Assault Rifle challenge fast even for low combat records: clear them, leave, and they respawn. The Car Factory also spawns the turquoise-and-black Special Elite enemies needed for the 25-kill Marksman Rifle task. Fear enemies for the 100-critical-kill Sniper challenge now spawn almost anywhere, so swapping to a sniper secondary opportunistically works well. The 300-kill LMG task, tied to a 40+ combat rating, is best saved for last so rating builds naturally. For Pistol and Launcher kills, grapple-into-wingsuit landings and midair-detonated GDL Havoc shots both track reliably, while a ballistic knife secondary lets Melee kills happen passively while hunting other targets.

Multiplayer Grind Tips

Nuke Town Covers Several Weapons

Nuke Town 24/7 suits SMG hip fires, Shotgun no-death streaks, and camping-based LMG kills, though skill-based matchmaking affects difficulty across the board. The 100-kill Assault Rifle task is easiest inside the TED Trials LTM. For Sniper headshots, completing the three-headshot requirement first in a match — before switching weapons — avoids wasted lobby time. Objective Melee kills require holding an actual objective point, such as B in Domination, rather than picking up kills near one.


Zombies Priority Order

Match Weapons To Modes

Early perk access, like a Perkaholic Gobble Gum in Nuke survival, speeds up Assault Rifle eliminations under Juggernog and Speed Cola. SMG progress needs the Rogue Run LTM, and the single-trial Shotgun task rewards packing and upgrading a shotgun before the TED Trial starts rather than mid-run. Elite enemies for the Sniper challenge don't spawn in every map, so survival modes in Ashes of the Damned are a safer bet. Legendary-rarity Launcher kills are easiest saved for later rounds once cash is available to upgrade rarity quickly.


Warzone Casual Routes

Bots Make This Mode Fastest

Casual lobbies—especially Call of Duty Black Ops 7 Bot Lobbies—make most Warzone tasks close to automatic. Ground loot Assault Rifle kills complete almost passively, and landing directly on a bounty target works better for the Pistol kill than trying to finish them off late. Keeping a Shotgun as a secondary until the top 10, and swapping to Melee against distracted bots after a weapon switch, both let challenges progress alongside normal play.

The table below compares where each mode's grind is fastest and what it demands from players.

Warzone and Endgame stand out as the most consistent modes since enemy density is high and skill requirements are low, while Multiplayer's difficulty swings the most due to matchmaking.


How Do You Get Guild Tech Kills Fast in Endgame?

Head to Car Factory or Old Arsenal, both tier one zones where robot-type Guild Tech enemies spawn in groups. Clear them with an Assault Rifle, leave the area, and return to trigger another spawn wave until 75 eliminations are reached.

Where Should You Farm Shotgun Kills in Multiplayer?

Nuke Town 24/7 works well for camping-based Shotgun challenges. Holding a building corner with stun grenades and an Akimbo-style shotgun helps secure three kills without dying across the required ten matches.

Which Zombies Map Has Elite Enemies for Sniper Camo?

Elite enemies for the four-kill Sniper challenge don't spawn in every map, so survival rounds in Ashes of the Damned, including the Diner, are a reliable option since Elite variants appear consistently there.

Is Warzone the Easiest Mode for Dark Matter Challenges?

Yes, largely because casual bot lobbies make most weapon-specific kills happen naturally during normal play. Ground loot Assault Rifle and early-game SMG kills in particular tend to finish without any dedicated farming route.

Quick Tips

· Save combat-rating-gated challenges, like the 300-kill LMG task, for last so the requirement is already met.

· Keep a secondary weapon (sniper, shotgun, or pistol) ready to swap into passively while working on a main challenge.

· In Zombies, upgrade weapons before starting single-trial challenges like the shotgun TED Trial rather than mid-run.

· Track Warzone-specific challenges externally, since several can be completed in the same match if timed correctly.


Who Benefits Most?

Beginners get clear, low-difficulty farming spots—especially through cheap CoD BO7 Bot Lobbies—that don't require a high combat rating or advanced aim. Endgame regulars get exact zone callouts that speed up otherwise RNG-based Guild Tech and Special enemy spawns. Zombies-focused players get mode-specific routing for challenges that don't work in every map, avoiding wasted runs. Together, these routes cut down the guesswork in reaching Dark Matter, letting players focus effort on the challenges that actually take time instead of the straightforward ones.
