Rex Infernus: Weapons

Wall weapons

Nineteen weapons hang on the walls of Rex Infernus, all of them Uncommon, from the CODA 9 for 500 Essence to the MK.78 and the XM325 for 2000. Two are in Her House, where the game starts: the CODA 9 and the Warden 308.

As everywhere in Black Ops 7, a wall weapon is bought at its rarity, and buying it again refills its ammunition. The Arsenal of the Nyxara Sanctuary raises the rarity and adds an Ammo Mod.

Mystery Box

A spin costs 950 Essence. The Box has several spots out in the Nexus, among them Ruinas Insula, Spira Insula, the Caltheris Main Chamber and the Dravakar Main Chamber; no source places one in Her House. It holds the arsenal of Black Ops 7, the TR51 Para, the VMP and the Roc 20mm since the update of October 15, 2026, and the special weapons of the map.

Warden’s Blight

The wonder weapon of the map, in the Box only once it has been earned through its quest.

Ray Gun and Ray Gun Mark II

The two classic wonder weapons, both in the Box.

Monkey Bomb and LT53 Kazimir

The special grenades of the map.

Wonder weapons out of the Box

Necrofluid Gauntlet

A wonder weapon given by Dravakar’s Anvil after a series of tributes: break down, at the anvil, one weapon of each class, each at Pack-a-Punch tier I at least: an assault rifle, a submachine gun, a pistol, a shotgun, a sniper rifle, a light machine gun, a marksman rifle, and a launcher or special weapon.

Void Claw

The grappling claw of the map, handed out free by its pedestals once the Pack-a-Punch is open.

The Void Claw, the Void Talon and the Pack-a-Punch

Corrupted weapons

Two Legacy Weapons of Season 5, the Stormwrought Pantheon shotgun and the Miserable Bastille marksman rifle, can be bought in a “Corrupted” Ultra form from a wall of Rex Infernus:

Buy the M10 Breacher, for the Stormwrought Pantheon, or the M34 Novaline, for the Miserable Bastille, from its wall.
Pack-a-Punch three other weapons.
Make an Astral Flame by pulling a spark into the Nexus Forge and turning the crank.
On the next rain round the wall weapon glows. Hit it with the Astral Flame; the pool of Veytharion can bring the rain early.
Kill the Web Mother that appears, then buy the Corrupted weapon from the wall.
The weapon drains the player’s health and cannot be put away: run to the Pack-a-Punch and upgrade it without going down. Downed, the weapon is lost, and the attempt starts again at the next rain round.

Stormwrought Pantheon

The Corrupted shotgun, earned from the wall of the M10 Breacher, at the Caltheris Entrance.

The Miserable Bastille

The Corrupted marksman rifle, earned from the wall of the M34 Novaline, in the Dravakar Sanctuary.

Once upgraded, it is used like any other weapon, and a trophy appears at the Nexus Forge with loot and Essence.
