Rex Infernus is the last round-based Zombies map Call of Duty: Black Ops 7 will ever get — the grand finale of the Dark Aether storyline and the end of a Zombies run that stretches back nearly two decades. It lands with Season 5 Reloaded on August 20, 2026 at 9 AM PT, and it arrives loaded: a new boss in the Warden, two brand-new enemy types, a Titan Trap, a new Perk-a-Cola, a new Ultra GobbleGum, two Ultra-Rarity Mystery Box weapons, and a Main Quest that plays out in both Standard and a brutal Cursed Mode. This guide covers exactly what's confirmed by Activision, when everything unlocks, what the Main Quest rewards, and how to be first to the Warden's inner sanctum.
Quick answer: Rex Infernus is Black Ops 7's final round-based Zombies map, releasing August 20, 2026 at 9:00 AM PT as part of Season 5 Reloaded (a free content drop, no extra purchase for BO7 owners). Its Main Quest goes live the moment the map does and is playable in Standard Mode (with guidance) and Cursed Mode (no guidance, limited HUD, starting pistol). Completing the Main Quest earns the "Bloodthorn" Wonder Weapon Skin, a Calling Card and 10,000 XP. The map adds the Deathspinner and Web Mother enemies, the Titan Trap, the Widow's Wine Perk-a-Cola, the Fully Packed Ultra GobbleGum, and two legacy Mystery Box weapons — the TR2 Marksman Rifle and Olympia Shotgun. If you just want the Easter egg cleared or high rounds banked without the grind, a Zombies boost does it for you.

What is Rex Infernus and when does it release?
Rex Infernus is the sixth and final round-based Zombies map in Black Ops 7, and it closes out the game's Dark Aether storyline. Activision confirmed the exact window in the Season 05 Reloaded announcement:
"The Main Quest for Rex Infernus will be available for play when the map releases with Season 05 Reloaded on August 20 at 9:00 AM PT." — Call of Duty Season 05 Reloaded blog, August 13, 2026
A few hard facts to anchor your plans:
| Detail | Confirmed |
|---|---|
| Release date & time | August 20, 2026, 9:00 AM PT |
| Update | Season 5 Reloaded (Mid-Season) |
| Map type | Round-Based Zombies (final one in BO7) |
| Cost | Free for Black Ops 7 owners |
| Main Quest live | At launch, 9:00 AM PT |
| Modes | Standard Mode & Cursed Mode |
| Livestream | ZombieZone on Aug 20 — pre-show 8 AM PT, race live 9 AM PT |
If you want to watch the community race the Easter egg live, Treyarch is running the Rex Infernus ZombieZone livestream on August 20 with creators cbgray and evanf1997 plus guest developers; tuning in on Twitch grants a unique Zombies emblem. That stream is also the fastest place to see the verified Main Quest steps the minute they're discovered.
Why does Rex Infernus matter so much?
Because it's the end. Rex Infernus is billed as the grand finale of the Black Ops 7 Zombies storyline — "as reality stands on the cusp of destruction, the crew face their ultimate challenge." Your objective, per the official synopsis, is to cleanse the Shadowsmith places of power, find the Warden's inner sanctum, and put an end to his existence.
The antagonist sets the tone himself:
"The end of your miserable lives is at hand." — The Warden
For long-time Zombies players this is a milestone map, not just another drop, which is why demand around it is spiking well before launch. It's also the last chance to grind BO7 Zombies camos and calling cards on fresh content before the mode's attention shifts to Modern Warfare 4 in the fall — so if a Dark Matter or mastery camo grind is on your list, the launch window is the time to push it. (See our fastest weapon XP and prestige guide for the leveling math.)
What are the new enemies in Rex Infernus?
Rex Infernus introduces two new threats built around webbing and swarming, plus the returning horde:
- Deathspinner (new enemy): Fast-moving creatures that strike quickly and use numbers to overwhelm the crew. They also fire a ranged web projectile that slows affected players. One-on-one they're manageable — the danger is when they swarm.
- Web Mother (new elite enemy): The scarier version. The Web Mother screams and lunges, uses heavy webbing to damage and slow the crew, and cocoons zombies to turn them into environmental hazards. Treat her like a mini-boss: create space, don't get pinned in a web field.
The practical takeaway: crowd control and mobility perks matter more on this map than raw damage. Anything that keeps you from getting slowed or surrounded — Stamin-Up, Widow's Wine (below), and the Titan Trap — is worth prioritizing early.
What is the Titan Trap?
The Titan Trap is Rex Infernus's signature environmental weapon. Per Activision, it draws in nearby zombies and smashes them to pieces — you "call upon the powerful force to slam their fists into the ground, damaging and disrupting zombies caught in the impact."
One warning straight from the patch notes: "Get out of the way fast when activating this trap or risk getting damaged by the Titan's flurry hits." So it's a high-value crowd-clear for tough rounds and Main Quest crunch points, but it will hurt you too if you stand in it. Learn its activation location and safe zone early.
What new Perk, GobbleGum and weapons are on the map?
Rex Infernus ships a full set of new Zombies toys:
| New item | What it does |
|---|---|
| Widow's Wine (Perk-a-Cola) | When melee attacks drop your health low, you retaliate with an explosion of webs that cocoons or slows enemies. Augments include Widow's Bite (melee kills on cocooned enemies overcharge health), Hatchling (web explosions summon a friendly Deathspinner), and Tangled Web (cocoons normal/special enemies, slows elites). |
| Fully Packed (Ultra GobbleGum) | Instantly upgrades your current weapon to Pack-a-Punch Level III in one bite. In Dead Ops Arcade it grants a Tactical Armor Vest or a full set of plates. |
| TR2 Marksman Rifle (Mystery Box, Ultra-Rarity) | New legacy weapon with stats rivaling a Wonder Weapon, full Pack-a-Punch progression and Ammo Mod support. Long-range picks. |
| Olympia Shotgun (Mystery Box, Ultra-Rarity) | New legacy weapon for up-close shredding — also full PaP and Ammo Mods. |
Widow's Wine is the standout. On a map built around webbing enemies, a perk that turns their own crowd-control against them — plus a summonable Deathspinner ally — is genuinely strong for both survival and the Main Quest. Prioritize buying it once you've secured Jugg and a damage perk.

How does the Rex Infernus Main Quest work?
The Main Quest is the map's Easter egg and the reason to grind Rex Infernus. It's playable in Standard Mode (normal HUD and guidance) and the harder Cursed Mode, and it goes live at 9 AM PT on launch day. Broadly, the objective is to cleanse the Shadowsmith places of power, locate the Warden's inner sanctum, and defeat him to end the storyline.
Completing the Main Quest earns:
- The "Bloodthorn" Wonder Weapon Skin, a Calling Card, and 10,000 XP.
- Collect the map's Intel — Audio Logs, Documents and Artifacts — for another Calling Card and a further 10,000 XP.
- Finish the quest before Directed Mode arrives for Rex Infernus to earn a unique Calling Card variant (a limited, prestige flex for early completions).
- Complete the Rex Infernus Mastery Challenge for an Animated Calling Card and 10,000 XP; each individual map challenge awards XP and a static Calling Card.
Important honesty note: the exact step order (activations, item locations, boss-fight mechanics) only exists once the map is live — Treyarch keeps it under wraps until 9 AM PT on August 20. This guide will be updated with the verified, official step-by-step on launch day. Anyone publishing a "full walkthrough" before then is guessing. For now, prep the fundamentals below so you can start the quest the second servers flip.
What is Cursed Mode?
Cursed Mode is Rex Infernus's built-in hard mode. Activision describes it as challenging you to "defeat the Warden's horde in even the most difficult situations," and it strips away your safety net:
- No Main Quest guidance (no on-screen step prompts)
- Limited HUD
- A starting Pistol instead of your usual loadout entry
It's aimed at veterans who want the toughest possible completion and the associated Pack-a-Punch camos. If you're chasing the storyline for the first time, do the Main Quest in Standard Mode first, learn the beats, then run Cursed Mode for the flex.
How do you beat Rex Infernus fast?
Until the verified steps drop, the winning move is preparation — the crews that finish first on launch day are the ones who don't waste the opening 20 rounds. A proven pre-launch checklist:
- Squad up and assign roles. Main Quests are far faster with a coordinated 2–4 player crew than solo. Decide who tracks Intel, who runs traps, who revives.
- Preload and patch early. Get the Season 5 Reloaded update installed the night before so you're in-game at 9 AM PT, not staring at a download bar. If you hit performance issues, our BO7 Zombies stutter and lag fix covers the packet-burst and frame-drop culprits.
- Bank a strong loadout going in. Bring a high-XP weapon you can Pack-a-Punch quickly; the Fully Packed GobbleGum is a shortcut straight to PaP Level III.
- Rush the essentials: Jugg-equivalent survival perk → damage → Widow's Wine → build toward the new Wonder Weapon. Learn the Titan Trap location and its safe zone.
- Grab the Mystery Box weapons. The TR2 Marksman Rifle and Olympia Shotgun hit like Wonder Weapons and cover long and short range respectively — solid insurance for boss phases.
- Watch the ZombieZone stream at 9 AM PT for live step discovery if you want to shadow the fastest route.
If the Easter egg, high rounds, or the Cursed-Mode camos aren't how you want to spend launch weekend, a CoD Zombies boost gets the Main Quest cleared and the rewards banked for you.
Skip the grind on the final map. timesaver.gg's pro players can knock out the parts of Rex Infernus you don't want to:
- CoD Zombies Boost — Main Quest completion, high rounds & camo grinding, done for you.
- BO7 Mastery Camo Unlock — Dark Matter and mastery camos across your arsenal.
- BO7 Account & Weapon Leveling — max your guns and account so you drop in already kitted.
- All Call of Duty services — every BO7, Warzone & Zombies boost in one place.
What else is in Season 5 Reloaded?
Rex Infernus is the headline, but the Aug 20 drop is stacked. Multiplayer gets the Turbo Tilt map (a playable Nuketown-themed pinball machine), the Freerun: Descent obstacle course, and the returning Cranked Moshpit LTM. Warzone brings back Black Ops Royale, adds Loaded Resurgence, and drops Special Delivery Drones you can shoot down for new camos. There's also the new Mace Melee Weapon and fresh attachments via Weekly Challenges. For the full rundown, see our Season 5 Reloaded: everything new guide and the Mace Melee weapon unlock guide.
