Absolute Zero is the icy tier-3 Warzone Mastery camo in Call of Duty: Black Ops 7 — the frost-blue finish that sits one rung below the reactive Apocalypse camo and acts as the final gate before it. It's the tier where the Warzone grind stops being a per-gun checklist and turns into an account-wide project, which is exactly why r/CODWarzone is full of players trying to figure out the smartest way to farm its signature "10 kills while in the Top 10" challenge. This guide breaks down the exact Absolute Zero requirement chain, the hidden 30-weapon gate most players don't see coming, and the fastest, verified way to knock out those Top-10 eliminations in Season 5.
Quick answer: To unlock Absolute Zero on a weapon in Black Ops 7, you must (1) unlock Starglass on that weapon, (2) unlock Starglass on 30 total weapons account-wide, and (3) get 10 eliminations while in the Top 10 with the chosen weapon. That middle step is the catch: Absolute Zero won't appear on any gun until you've already pushed 30 different weapons to Starglass. The 10 Top-10 kills are cumulative across matches (not a single-game challenge), so you can chip away at them in any mode that reaches a Top 10 — including fast, low-stakes lobbies. Do it on 30 weapons and the reactive Apocalypse camo unlocks as a universal reward.

What is the Absolute Zero camo in Black Ops 7?
Black Ops 7 runs a four-tier Warzone Mastery camo ladder, and Absolute Zero is Tier 3 of it. The full progression is:
| Tier | Warzone Mastery camo | Per-weapon challenge |
|---|---|---|
| 1 | Golden Damascus | Get 3 kills in a single match, 5 times |
| 2 | Starglass | Get 5 kills without dying, 5 times |
| 3 | Absolute Zero | Get 10 eliminations while in the Top 10 |
| 4 | Apocalypse (reactive) | Unlock Absolute Zero on 30 weapons |
Absolute Zero is where the grind changes character. The first two tiers, Golden Damascus and Starglass, are pure per-weapon work — do the challenge on the gun and move on. Absolute Zero adds an account-level gate: the camo challenge itself only becomes available once your Warzone Mastery progress hits a threshold across many weapons. As gfinityesports puts it, Absolute Zero is "not a single-weapon checklist" and "requires account-level progress through the Warzone Mastery system before the camo appears."
In plain terms: you can't cherry-pick one favorite gun and rush it straight to Absolute Zero. The game wants proof you've mastered a wide slice of the arsenal first.
What are the exact Absolute Zero requirements?
There are three conditions, and they must all be true for a given weapon. Per pcgamesn's official-challenge breakdown, the in-game requirements for Absolute Zero read:
| Step | Exact requirement | What it means |
|---|---|---|
| 1 | "Unlock Starglass on your chosen weapon" | That specific gun must already have the tier-2 camo |
| 2 | "Unlock Starglass on 30 Weapons" | Account-wide gate — 30 different guns at Starglass |
| 3 | "Get 10 Eliminations while in the Top 10 with your chosen weapon" | 10 late-game kills, cumulative across matches |
The headline challenge is that last line, quoted verbatim from the in-game tracker: "Get 10 Eliminations while in the Top 10 with your chosen weapon." Only kills you earn after your squad has already reached the Top 10 count. There are no kill-streak, placement, or survival sub-conditions — as gfinity notes, there are "no requirements for kill streaks, placement targets, or survival bonuses." You just need ten late-circle eliminations on that gun, and they stack across as many matches as it takes.
Step 1 — Starglass on your chosen weapon
Before Absolute Zero can even show up on a gun, that gun needs Starglass — Tier 2. Starglass itself requires you to unlock Golden Damascus on the weapon, unlock Golden Damascus on every weapon in its class, and then get 5 kills without dying, 5 times with the weapon. So each Absolute Zero weapon is already a fully-mastered gun by the time you start the Top-10 grind.
Step 2 — Starglass on 30 weapons (the hidden gate)
This is the requirement that catches people out. Absolute Zero's challenge stays locked until you've earned Starglass on 30 separate weapons. That's a huge amount of upstream work — 30 guns each cleared through the entire Military → Special → Golden Damascus → Starglass chain. It's why so many players report the camo "not showing up" on a weapon that clearly has Starglass: the gun is ready, but their account hasn't hit 30 Starglass weapons yet. (If it is showing as bugged even after 30, see our Absolute Zero not-tracking fix.)
Step 3 — 10 eliminations while in the Top 10
Once both Starglass conditions are met, the Absolute Zero challenge finally appears on your eligible weapons: 10 eliminations while in the Top 10. These are cumulative, so you never have to get all ten in one match — one or two late-game kills per game slowly ticks the counter to ten.
What's the fastest way to farm the Top-10 kills?
Because the 10 eliminations are cumulative and only need to happen while you're in the Top 10, the fastest method is to play modes where reaching the Top 10 is quick and frequent — not slow, 150-player big-map matches where one death ends your run. Players grinding it right now report finishing the Top-10 requirement across their whole arsenal in a couple of days by doing exactly that. Here's the optimal approach:
- Play fast, small modes. Resurgence and limited-time modes (LTMs) with smaller lobbies get you into the Top 10 far more often per hour than standard battle royale. More Top-10 phases per hour = more chances to bank kills. One r/CODWarzone grinder summed it up: LTMs "just speed up the process."
- Treat it as cumulative, not per-match. Don't force all ten in one game. Land one or two late-circle kills, extract or reset, and repeat. Ten kills on a gun comes fast once you stop trying to hero every match.
- Batch it with your Starglass grind. Every match you play toward the 30-weapon Starglass gate is also a match where you can bank Top-10 kills on guns that already have Starglass. Don't silo the two grinds.
- Do the awkward weapons deliberately. Launchers, melee, and specials are painful to farm Top-10 kills with in normal lobbies. Grinders specifically use easy LTM lobbies to "get them out of the way" — knocking out the hard weapon classes when the lobby is soft is far less frustrating.
- Use low-pressure lobbies for the ugly classes. The whole challenge is a survival-to-Top-10 numbers game, so anything that lowers lobby difficulty — easier bot-style lobbies, off-peak hours, or LTMs — directly speeds up the melee and launcher portions.
Even done efficiently, Absolute Zero on a single weapon is a serious commitment because of the 30-weapon Starglass wall behind it. The Top-10 kills are the easy part; getting 30 guns to Starglass first is the mountain.
How does Absolute Zero lead to Apocalypse?
Absolute Zero isn't the finish line — it's the last checkpoint before Apocalypse, the reactive red-energy Warzone Mastery camo that's the real battle-royale flex. Apocalypse has exactly one requirement: unlock Absolute Zero on 30 weapons.
So the endgame math stacks up like this:
- 30 weapons must reach Starglass before Absolute Zero unlocks on any of them.
- Then each of those weapons needs its own 10 Top-10 kills to earn Absolute Zero.
- Once 30 weapons have Absolute Zero, Apocalypse pops as a universal, account-wide reward.
That's why Absolute Zero is the tier that separates casual camo-chasers from the players actually going for Apocalypse. If you're planning to grind Apocalypse, every Absolute Zero you bank is one of 30 you'll ultimately need — there's no shortcut around the 30-weapon requirement.

Does Season 5 change the Absolute Zero grind?
Warzone and Black Ops 7 Season 5 went live on July 23, 2026. The Absolute Zero requirement chain itself is unchanged — Starglass-on-weapon → Starglass-on-30 → 10 Top-10 kills is fixed. What Season 5 adds is new weapons, and every new gun is another eligible weapon for the per-weapon tiers and another candidate toward both 30-weapon gates (Starglass for Absolute Zero, Absolute Zero for Apocalypse). New weapons usually launch with a Double Weapon XP window, so folding fresh Season 5 guns into your Starglass grind while the boost is live is the efficient play. Weapon level progress is shared across Black Ops 7 and Warzone, so leveling those new guns pulls double duty.
Is Absolute Zero worth grinding?
If your target is Apocalypse, Absolute Zero isn't optional — it's the mandatory tier-3 gate on all 30 weapons you need, so the honest question is whether the Apocalypse road is worth it. For battle-royale players who want the rarest reactive finish in the lobby, yes: it's one of the clearest "I have beaten this game's progression" badges in Black Ops 7, and Absolute Zero is the tier where most people stall out. Its frost-blue finish is also a genuinely clean cosmetic on its own if you never plan to push to Apocalypse.
The requirement is pure time and consistency — 30 weapons through the entire Warzone camo chain, then ten late-circle kills each — not skill or luck. That's exactly the kind of long, grindy commitment that's worth boosting if your schedule can't absorb hundreds of Warzone matches.
Skip the grind: the 30-weapon Starglass wall behind Absolute Zero is one of the longest cosmetic grinds in Black Ops 7.

FAQ
How do you unlock Absolute Zero in Black Ops 7? Unlock Starglass on your chosen weapon, unlock Starglass on 30 total weapons account-wide, then get 10 eliminations while in the Top 10 with that weapon. All three conditions must be met — the Top-10 challenge stays locked until you've hit 30 Starglass weapons.
Do the 10 Top-10 kills have to be in one match? No. They're cumulative across matches. You can bank one or two late-circle kills per game and the counter carries over, so you never have to get all ten in a single Warzone session.
Why isn't Absolute Zero showing up on my weapon? Almost always the 30-weapon Starglass gate: the gun has Starglass, but your account doesn't have Starglass on 30 different weapons yet, so the challenge is still locked. If you genuinely have 30 Starglass weapons and it's still not appearing, it may be a tracking bug — see our Absolute Zero not-tracking fix.
What's the fastest way to farm the Top-10 eliminations? Play fast, small modes like Resurgence and LTMs where you reach the Top 10 often, and treat the ten kills as cumulative rather than forcing them in one game. Easier or lower-population lobbies make the melee, launcher, and special-weapon versions of the challenge much quicker.
Does multiplayer or Zombies progress count toward Absolute Zero? No. Absolute Zero is on the Warzone camo track, so its challenges must be completed in Warzone. Multiplayer and Zombies each have their own separate Mastery camo paths. Weapon level is shared across modes, but camo challenges are mode-specific.
What comes after Absolute Zero? Apocalypse, the reactive Warzone Mastery camo. It unlocks as a universal, account-wide reward once you've earned Absolute Zero on 30 total weapons.
