Rex Infernus: How to Use the Void Claw Grapple in BO7 Zombies

Grab the grapple after opening Pack-a-Punch, then use its 30-second window to cross the map and pull loot orbs.

Grab the grapple after opening Pack-a-Punch, then use its 30-second window to cross the map and pull loot orbs.

The Void Claw is the grapple hook tied to Rex Infernus, the final round-based Zombies map in Black Ops 7. It lets you cross gaps fast, break away from a crowd of zombies, and drag floating purple orbs across the map to shake out extra loot. Getting it is straightforward once Pack-a-Punch is open, but the way it works has a few rules that will punish careless play.

Quick answer: Finish the Pack-a-Punch quest at the Nexus Forge, then grab the Void Claw from the green orb pedestal beneath the Forge. In matches, recharge it at any active Void Pedestal (the one glowing with a green orb) and it replaces your Tactical Equipment for 30 seconds of unlimited grappling.

Unlock the Void Claw through the Pack-a-Punch quest

You cannot pick up the Void Claw until Pack-a-Punch is running. That whole setup takes place at the Nexus Forge, the hub at the center of the map, and it starts inside the spawn area known as Her House.

Hold out in Her House and clear zombies until you reach around Round 3. A phone will start ringing on the lower floor. Answer it to open the front door, then walk through the portal on the cliff edge outside to reach the Nexus Forge.

Place the World Seed on the central pedestal at the Forge. This frees two flying red Dread Skulls that lead you toward the Main Chambers. Chase each one, deal enough damage to destroy it, and it will drop into a cauldron holding the Usurped Flame.
Take the Usurped Flame from the cauldron and carry it back to the Forge, then throw the fireball to light one of the two braziers beside the center pedestal. Repeat the chase for the second skull and light the second brazier.
With both braziers lit, rotate the two crank wheels near the Forge platform. The platform lowers, golden rings and runes activate, and the Pack-a-Punch machine rises in the center. Head into the newly opened doorway below the Forge and interact with the green orb on the pedestal to claim the Void Claw.

You will know it worked when the grapple registers as your equipped tool. The only requirement to grab it is finishing the Pack-a-Punch quest, so if the pedestal is inactive, both braziers or a crank wheel are still incomplete.


Recharge it at Void Pedestals during a match

After you first claim it, the Void Claw is charged from Void Pedestals scattered around the map rather than only from the Forge. An active pedestal shows a green orb you can interact with, and interacting hands you a fresh charge.

There are only a limited number of active pedestals per round. Once you use them up, the pedestals go quiet and new ones light up in different spots when the next round begins. If you cannot find a charge, move to the next round and look for a different glowing pedestal.

How the Void Claw works when active

Activating the Void Claw replaces your Tactical Equipment slot for 30 seconds. During that window you get unlimited grapples, so you can chain pulls across the map without waiting for a cooldown. Aim and fire it to pull yourself toward a surface, and if you press jump right as you reach the anchor, you launch upward faster than a normal grapple pull.

PropertyBehavior
Slot usedReplaces Tactical Equipment for 30 seconds
Uses per chargeUnlimited within the 30-second window
Extra heightFire the claw, then press jump to propel upward faster
RangeFairly short compared with a standard grapple
Out-of-boundsTeleports you back to the ground with half health

The range is limited, so treat it as a mobility tool for crossing the map and escaping crowds rather than reaching far rooftops. If you grapple into an out-of-bounds area, the game snaps you back down to the ground and cuts you to half health, which is a real risk mid-round. Avoid using it to climb onto roofs or under the map.

Pull purple orbs for Salvage and Equipment

Beyond travel, the Void Claw pulls the floating purple orbs seen around the map. Grapple an orb toward you and interact with it, and it drops Salvage and Equipment. This is one of the fastest ways to top up crafting materials mid-run.

For a bigger payout, drag the orb next to a skeleton before you interact with it. Pulling an orb onto a skeleton and then triggering it drops noticeably more loot than a plain interaction.

The same pull mechanic feeds the dig sites dotted around the exterior areas such as Caltheris’ Passage and Aranea Insula. These look like dirt mounds with bones. Use the Void Claw to drag a purple orb from the Nexus Forge sky into a dig site so it gets absorbed, and once the site is glowing you can open it with the claw to reveal its loot. Working through several dig sites this way is also the opening step toward the Mister Peeks cassette secret.

Note: Because charges are capped per round and the tool only stays active for 30 seconds, plan your orb pulls and traversal in advance. Line up the orbs or ledges you want, then activate the claw so you spend the window moving instead of hunting for targets.
