Rex Infernus is the final round-based Zombies map for Call of Duty: Black Ops 7, and it launches with the Season 5 Reloaded update — expected around the end of August 2026, roughly a month after Season 5 went live on July 23. It closes out the Black Ops 7 Zombies storyline on a remake of Dr. Monty's house from Revelations, and it drops in a new Wonder Weapon, the returning Widow's Wine Perk-a-Cola, a new Fully Packed GobbleGum, and the Olympia shotgun and TR2 marksman rifle as Ultra-Rarity legacy weapons.

- Setting: A recreation of Dr. Monty's estate — the house from Black Ops III's Revelations. "Rex Infernus" is Latin for King of Hell.

- How to be ready day one: Bank GobbleGums, level your best Zombies weapons, and get your camo grind close before Reloaded — the details are below.
Per the official Call of Duty Blog, Season 05 Reloaded includes "Rex Infernus, the new Round-Based Zombies map" — Treyarch's send-off for the Black Ops 7 undead saga.
Season 5 has been one of the busiest stretches of the year for Black Ops 7, and Reloaded is the finale. If you've been holding onto GobbleGums or debating which camo to chase next, this is the map to prepare for. Here's every confirmed detail, the realistic release timing, and exactly how to get ready so you're not grinding basics on launch night.
When does Rex Infernus release?
Rex Infernus arrives with Season 5 Reloaded, the mid-season update for Black Ops 7 and Warzone. Season 5 itself went live on July 23, 2026 at 9 AM PT / 12 PM ET / 5 PM BST, and "Reloaded" updates historically land about four to five weeks into a season — which puts Rex Infernus at roughly the end of August 2026.
Activision has confirmed the map for Reloaded but has not published an exact release date or unlock time as of this writing. When it does, expect the standard cadence: a Call of Duty Blog post a day or two ahead, followed by a global unlock in the morning Pacific window. We'll update this guide the moment the date is official.
| Milestone | Date / window | Status |
|---|---|---|
| Season 5 launch | July 23, 2026 (9 AM PT) | ✅ Live |
| Season 5 Reloaded update | ~Late August 2026 | ⏳ Confirmed, date TBA |
| Rex Infernus map | With Reloaded (~late Aug) | ⏳ Confirmed |
| Exact unlock time | 9 AM PT expected | ⏳ Unannounced |
Because Rex Infernus is the last round-based map of Black Ops 7's DLC cycle, this is effectively the Zombies finale before the game's post-launch content winds down — so demand and lobby traffic on launch day will be heavy.
What is Rex Infernus? Setting and story
Rex Infernus recreates the house from Revelations — Dr. Monty's estate, one of the most recognizable locations in Treyarch Zombies history. Longtime players will remember the mansion and its warped, otherworldly geometry from the Black Ops III map that closed out the original Aether storyline. Bringing it back for the final Black Ops 7 map is a deliberate bookend.
The name itself sets the tone: "Rex Infernus" is Latin for "King of Hell." Everything revealed so far points to a high-stakes, story-concluding map rather than a casual side experience — this is the one the season has been building toward.
Treyarch has leaned into narrative-heavy finales before, and the Revelations homage tells you what to expect: a dense map, a full main quest (Easter egg), and callbacks for players who've followed the Black Ops 7 story from launch. Exact quest steps aren't public until the map goes live, so treat any "full walkthrough" you see before release with skepticism — nobody has completed the Easter egg yet.
Rex Infernus new content: Wonder Weapon, perks, and legacy guns
Season 5 Reloaded bundles several confirmed additions alongside the map. Here's what's official:
- A new Wonder Weapon — confirmed for the map, name not yet officially revealed. Wonder Weapons are usually build-defining, so this is the headline pull.
- Widow's Wine (Perk-a-Cola) — the fan-favorite perk returns. Widow's Wine historically slows and damages nearby zombies when you're hit and adds a web grenade, making it a survival staple on high rounds.
- Fully Packed (GobbleGum) — a new GobbleGum joining the rotation for Reloaded.
- Olympia shotgun + TR2 marksman rifle — both arrive as Ultra-Rarity legacy weapons, continuing Black Ops 7's habit of reviving classic guns for Zombies.
| Content | Type | Notes |
|---|---|---|
| New Wonder Weapon | Wonder Weapon | Confirmed; name TBA |
| Widow's Wine | Perk-a-Cola | Returning fan favorite |
| Fully Packed | GobbleGum | New for Reloaded |
| Olympia | Legacy shotgun | Ultra rarity |
| TR2 | Legacy marksman rifle | Ultra rarity |
If you want the Wonder Weapon fast on day one, that usually means either the main quest route or a Mystery Box grind — so having GobbleGums that improve Box luck or guarantee pulls is worth banking now.

Will Rex Infernus have a Directed Mode?
Treyarch has shipped Directed Modes with recent Black Ops 7 Zombies content — the guided, step-by-step version of a map's Easter egg with an on-screen objective tracker and a round cap. Kowakujō received a Directed Mode this season, and the feature has become a standard follow-up rather than a launch-day guarantee.
Expect a Rex Infernus Directed Mode to arrive, but likely after the standard map release, not alongside it — Treyarch typically lets the community race the Easter egg "raw" first, then adds Directed Mode later. If you want the guided experience for the finale, it's usually worth waiting a week or two after launch. Our BO7 Kowakujō Directed Mode Easter egg guide shows how that flow works if you're new to Directed Mode.
How to prepare for Rex Infernus before it drops
You have roughly a month before Reloaded. Use it. The players who complete the Easter egg fastest and hit high rounds day one are the ones who walk in already stocked. Here's the prep checklist:
- Bank GobbleGums. Stock up on high-value classics (Perkaholic, Near Death Experience, and anything that improves Box pulls) plus the new Fully Packed. You earn them passively — start hoarding now so you're not empty-handed on the finale.
- Level your Zombies loadout. Get your go-to Zombies weapons to max so you're not wasting the first hours leveling instead of pushing rounds or the quest. If the grind is brutal, our BO7 Zombies XP farm guide covers the fastest routes.
- Close out your camo grind. Reused camo progress carries between maps. Finishing weapon camos before Reloaded means the new map is pure content, not chore-time — see the BO7 Zombies camos unlock guide.
- Finish current-map objectives. If you still owe yourself the Eidskallen Lighthouse rewards or Kowakujō completions, wrap them now — attention (and lobbies) shift hard to Rex Infernus at launch.
- Sort your Battle Pass. Reloaded refreshes Battle Pass content; if you're behind on the current Season 5 Battle Pass, close the gap before the new tier pressure hits.
Doing all of this in a month is a grind — realistically 20–40+ hours of Zombies depending on how much you've already banked. If you'd rather show up ready without burning the runway, that's where a boost comes in.
Skip the pre-finale grind and walk into Rex Infernus ready. Our pros handle the parts you don't want to:
- CoD Account & Weapon Leveling — max your Zombies loadout before Reloaded, fast and secure.
- CoD Mastery Camo Unlocks (BO7) — close the camo grind so the new map is all fun.
- All Call of Duty services — leveling, camos, ranked, and more for Black Ops 7 and Warzone.
Is Rex Infernus really the last Zombies map for Black Ops 7?
Yes — Rex Infernus is described as the final round-based DLC map, the one that closes the Black Ops 7 Zombies storyline. That doesn't necessarily mean the absolute end of all Zombies updates (events, playlists, and tuning can continue), but it is the last new round-based map on the current roadmap. For story players, this is the finale — which is exactly why the Revelations callback matters.
