rex infernus guide: Step-by-Step Wonder Weapon Walkthrough

Rex Infernus is the final Round-Based Zombies map in Black Ops 7, and the Warden’s Blight Crossbow is its featured Wonder Weapon. The weapon uses dual-wield crossbows with a charge attack that creates explosive fire tornadoes, making it especially useful when several Zombies pressure the team at once.

The unlock route begins only after Pack-a-Punch is active. You will need a grapple gun, PhD Flopper, Astral Fire, a Purple Crystal, and enough time to complete a light-beam puzzle inside Nyxara’s Sanctuary. After that, the tree in the hidden forest leads you to the three weapon parts.

Video Highlights:

• Pack-a-Punch must be activated before the grapple-gun steps become available.
• Purple orbs are carried back to the central forge with the temporary grapple gun.
• The Astral Fire powers the beam puzzle in Nyxara’s Sanctuary.
• The final crossbow is crafted above Dravikar’s Main Chamber.

The Wonder Weapon quest becomes available after you activate Pack-a-Punch at the Nexus Forge. The opening section starts in an abandoned house, where the team must hold out until the phone rings. Interact with the phone after the event begins, then use the exterior portal to reach the forge.

At the Nexus Forge, place the World Seed to spawn two red flying skulls called Dread Skulls. Each skull travels to a different location. Follow the target, seize the Usurped Flame, and return it to the matching brazier at the forge.

The first skull leads toward the forge route, while the second sends the team toward the Caltheris Main Chamber. Destroying the second skull also summons a large Titan that pounds the ground. Keep your distance and avoid standing in the impact area while finishing the encounter.

Once both braziers are lit, rotate the Crank Wheels around the forge. The Nexus Forge descends beneath the ground, runes illuminate, and a staircase forms around the platform. When the sequence ends, Pack-a-Punch is active.

The house piano can also be interacted with, but it is connected to a later puzzle rather than the Warden’s Blight crafting route. Do not spend time searching for a weapon part during the opening holdout.

This is the central Rex Infernus Wonder Weapon route. The order below keeps the required items together and reduces unnecessary travel between temples.

The beam puzzle is timed, so expect to use more than one grapple-gun charge and more than one Astral Fire pickup. The important goal is not speed alone; it is keeping the beam moving through the correct crystal sequence before the temporary tools expire.

The Silent Area is a dark forest containing the pieces of the Warden’s Blight Crossbow. The available route descriptions identify three major search points: a corpse beside a cave, a corpse near a central rock, and a body near a burned cabin or broken structure.

There is an important variation to account for. Some instructions describe all three bodies appearing during one forest visit, while another route describes collecting one part per visit and advancing a round between visits. If your area contains only one active part, leave safely, advance the round, return to the tree, and repeat the fruit sequence.

After collecting all three pieces, return to Dravikar’s Main Chamber. Blue symbols on the wall introduce a riddle involving the Star, Moon, Runner, and Galaxy symbols. The solution changes between matches, so a fixed combination should not be copied from another game.

Listen to Dravikar’s clue and inspect the writing around the puzzle room. The riddle explains how the symbols should relate to one another. For example, a clue stating that the Star follows the Moon means the Star pillar must be rotated to point toward the Moon.

A community-made Dravakar temple puzzle solver can help translate the riddle into switch rotations. Use the solver only after identifying the riddle variant in your match.

When the four-symbol puzzle is correctly aligned, interact with the middle pillar. The top of Dravikar’s temple opens, revealing a grapple route into a hidden chamber. Grapple through the opening and locate the forge.

Interact with the forge while all three Warden’s Blight parts are in your inventory. The weapon is crafted there, and no separate upgrade quest is currently required before using it with Pack-a-Punch. Once assembled, take the crossbow to Pack-a-Punch if you want to improve its damage for later Main Quest objectives.

The charged attack creates explosive fire tornadoes that can clear groups and damage clustered enemies. Use normal shots for routine targets, then reserve the charged effect for a tight horde, an emergency escape, or a dangerous objective phase.

The crossbow is also useful outside the crafting sequence. Its explosive fire tornadoes can create breathing room when Deathspinners slow the team with web projectiles. The Web Mother remains a major threat because it can lunge, scream, spread damaging webs, and cocoon Zombies.

The map’s Titan Trap can provide additional crowd control, but players should avoid standing too close when it activates. The Titan’s ground attacks can affect nearby players as well as Zombies.

The Rex Infernus Main Quest rewards the Bloodthorn Wonder Weapon Skin, a Calling Card, and 10,000 XP. Completing the quest before Directed Mode releases also provides a unique Calling Card variant. These rewards are separate from the crossbow crafting step, which gives you the Wonder Weapon needed for continued progression.

Additional map rewards include Intel-related rewards and a Mastery Challenge. The map also adds new content such as Deathspinners, the Web Mother, the Titan Trap, Widow’s Wine, Fully Packed, the TR2 Marksman Rifle, and the returning Olympia Shotgun.

Common mistakes include attempting the temple route before Pack-a-Punch, arriving at Nyxara’s Sanctuary without Astral Fire, leaving the Silent Area before confirming a part pickup, and treating the Dravakar riddle as a universal code.
