Rex Infernus, the final round-based Zombies map in Call of Duty: Black Ops 7, hides nine free Power-Ups across its sanctuaries and outer ledges. Each one is a physical pickup you have to spot and shoot (or destroy with C4) to spawn it, and grabbing all of them is its own small side Easter Egg that ends with two bonus drops appearing at once.
Quick answer: Collect Max Ammo, Double Points, Nuke, Full Power, Max Armor, Bonus Points and Insta Kill from the seven fixed locations below. Once all seven are claimed, the Fire Sale spawns at Spira Insula and the Random Perk spawns at Aranea Insula.
How the Power-Up hunt works
Seven Power-Ups sit in fixed spots and can be grabbed in any order. Most are tucked behind walls, on distant buildings, or high on ceilings, so you either shoot them directly or stick a C4 charge to save the pickup for a moment when you actually need it. The last two, the Fire Sale and the Random Perk, only become available after the first seven are gone.
Note: A compass heading (for example, 196) refers to the number shown on your in-game compass while aiming toward a distant Power-Up. Line the number up before you fire.
The seven fixed Power-Up locations
| Power-Up | Where to find it |
|---|---|
| Max Ammo | Inside Her House, the starting area. Go to the bottom floor and melee the painting by the fireplace on the west side, then crouch to the right to reveal the drop. |
| Double Points | At Caltheris Passage, just before Caltheris Entrance. Take a right toward the edge of the ledge and aim south at about 196 on the compass, on a pillar by a distant temple. |
| Nuke | From the Caltheris Main Chamber, step onto the platform leading to Ruinas Insula. Look north-east at about 75 on the compass toward the building. |
| Full Power | At the Veytharion Main Chamber. Look up and to the left of the Arsenal Machine, on the ceiling at the corner of the pillar. |
| Max Armor | At Dravakar Entrance. Head to the first zombie barricade on the left (the hole in the wall) and check the left corner behind the broken section. |
| Bonus Points | At Nyxara Passage. Turn left by Stamin-Up to find an opening, then aim south at about 155 on the compass. |
| Insta Kill | At the Nyxara Main Chamber. Move to the top-left corner by the fiery drop and look down, near one of the pillars. |
If you have already left Her House, you can return through the map’s normal traversal path to reach the Max Ammo behind the painting.
Fire Sale and Random Perk (spawn after the first seven)
Both of these only appear once every other Power-Up has been collected, and they spawn together. Finish the seven above first, then head to the islands.
Fire Sale: Go to Spira Insula, the island sitting between Nyxara Sanctuary and Veytharion Sanctuary. Stand at the Mystery Box spawn and aim toward the distant building at about 336 on the compass.
Random Perk: Travel to Aranea Insula, the north-side island that holds Widow’s Wine. Move to the north-west island and look down toward the bridge in the distance. The drop sits on the far-right side of that bridge.
You will know the chain is complete when both the Fire Sale and Random Perk are available at the same time. If either one refuses to appear, you still have one of the earlier seven Power-Ups left to grab.
Because several pickups sit on ledges or high on pillars, a C4 charge is often more reliable than a rifle shot, and it lets you bank the Power-Up until a round when the effect matters most. Work through the sanctuaries in whatever order fits your run, save the two islands for last, and you will clear all nine without backtracking.
