Her House: Your First Two Wall Buys
Warden 308
The Warden 308 is available immediately in the first room where you spawn inside Her House. It is an excellent early option when you need a reliable weapon without traveling far.
Coda 9
The Coda 9 is the second Wall Buy in Her House. Head upstairs and look beyond the barricade from the starting room.
Key takeaway: Her House gives you two convenient early-game weapon options before you begin exploring the rest of Rex Infernus.
Nexus Forge and Nexus Core Weapons
Ryden 45K
Travel to the Nexus Forge, where the Ryden 45K can be found on the western side before the Nyxara Passage.
MK.78
The MK.78 is located in the Nexus Core, directly beneath the Nexus Forge. However, reaching this area requires completing the Pack-a-Punch quest first.
Key takeaway: The Nexus area provides useful upgrades as you progress deeper into the map.
Nyxara: Multiple Powerful Options
Echo 12
The Echo 12 is located in the Nyxara Passage, far north of the Stamin Up machine near a large rock.

At the Nyxara Entrance, head north just beyond the doorway to find the Peacekeeper Mk1.
VS Recon
The VS Recon sniper rifle is positioned on the south wall of Nyxara Sanctuary, just beyond the Arsenal Machine.
DS20 Mirage
The DS20 Mirage is found on Spira Insula, the floating island between Nyxara Sanctuary and Veytharion Sanctuary. The island also contains the Jugger-Nog machine.
Key takeaway: Nyxara and the surrounding island offer a strong mix of close-range, assault, and sniper weapons.
Caltheris and Ruinas Insula Wall Buys
M10 Breacher
The M10 Breacher is located at the Caltheris Entrance, east of Nexus Forge and north of the Wisp Tea machine.
X9 Maverick
You can find the X9 Maverick farther through the Caltheris Entrance, on the south wall of the hallway.

Head to Ruinas Insula, the floating island between the Dravakar Main Chamber and Caltheris Main Chamber. The M15 MOD 0 is located here near the area containing the PHD Flopper machine.
Key takeaway: Caltheris provides several practical weapon choices while traveling between major areas.
Veytharion and Dravakar Locations

The Dravec 45 sits on a ledge above Dravakar Passage, northeast of Nexus Forge.
AK-27
The AK-27 is on the second floor of Dravakar Main Chamber on the southern side. You can reach the platform through a wall jump from either side or by using the Void Claw.
M34 Novaline
The M34 Novaline can be found on the wall to the left inside Dravakar Sanctuary.
Key takeaway: Veytharion and Dravakar contain some of the most useful mid-to-late-game Wall Buys, so remember their locations during longer runs.
Aranea Insula: The Final Weapon Stops
XM325
The XM325 LMG is located at Aranea Insula, the floating island on the far northern side of the map. This is also where you can find Widows Wine.
XR3-ION
The final Wall Buy is the XR3-ION sniper rifle, also located on Aranea Insula, specifically on the southern side.
Key takeaway: Aranea Insula contains the final two Wall Buys and is worth remembering for players who prefer heavy or long-range weapons.
Armor Vest Locations
Rex Infernus also includes several locations where players can find Level II and Level III Armor Vests:
·Nyxara Sanctuary
·Caltheris Main Chamber
·Dravakar Sanctuary
·Veytharion Sanctuary
These armor locations are particularly valuable during high-round attempts and difficult Main Quest stages.
Helpful Tips for Rex Infernus
1. Memorize Her House first. These two Wall Buys are available immediately.
2. Track your route between islands. Knowing nearby Wall Buys can save valuable time.
3. Don't ignore Armor Vests. Higher-tier armor becomes increasingly important in difficult rounds.
4. Complete the Pack-a-Punch quest early if you want access to the MK.78 location.
5. Remember movement routes. Wall jumps and the Void Claw can help you reach elevated weapons such as the AK-27.
6. Use Wall Buys as emergency backups. They can be lifesavers when your ammunition runs low.
7. Match weapons to your strategy. Snipers, shotguns, assault rifles, and LMGs each serve different purposes.
Final Verdict: Master the Map, Master the Zombies
Rex Infernus offers a surprisingly diverse collection of Wall Buys spread across Her House, Nexus Forge, Nyxara, Caltheris, Ruinas Insula, Veytharion, Dravakar, and Aranea Insula. Learning these locations means you can quickly replace an underperforming weapon, recover after running out of ammunition, and prepare for increasingly difficult rounds.
For casual players, this list makes exploration easier. For Main Quest hunters, it provides a useful reference when planning routes. High-round specialists can memorize emergency weapon locations, while speedrunners can use the information to optimize movement between objectives. Players looking to accelerate their setup can also buy CoD Black Ops 7 Bot Lobbies at MMOEXP and get back to experimenting with Rex Infernus builds and strategies.
