Rex Infernus is a sprawling map, and the walls are still the cheapest way to stay armed while you work through the main quest. Nineteen weapons hang on walls across the map, spread between Her House, the Nexus hub, the four temple regions, and the floating islands. Knowing which gun sits where saves you the salvage and the detour.
Quick answer: Every wall buy is reachable on a normal run except two. The MK.78 sits in the Nexus Core, which only opens after you finish the Pack-a-Punch quest, and the AK-27 is on the second floor of the Dravakar Main Chamber, which needs a wall-jump or the Void Claw.

Her House wall buys: Warden 308 and Coda 9
The Warden 308 is mounted in the very first room you spawn into, so it’s the first gun you can realistically afford. The Coda 9 is the only other wall buy inside the house, sitting upstairs just past the barricade off the starting room. Once you leave through the portal, you’ll need a separate route to get back into the house later, so pick these up early if you want them.
Nexus Forge and Nexus Core wall buys
The Nexus Forge is the hub you teleport into after answering the phone, and the Ryden 45k is stuck on the west side of it, right before the path into the Nyxara Passage. It’s the most convenient early SMG on the map given how often you’ll pass through the center.
Directly beneath the Forge is the Nexus Core, home to the MK.78 light machine gun. That lower area stays sealed until you lower the central platform during the Pack-a-Punch quest, so treat this one as a mid-run purchase rather than an opener.
Nyxara wall buy locations
The Nyxara side of the map holds three weapons across its entrance, passage, and sanctuary.
- Echo 12 — in the Nyxara Passage, well north of the Stamin-Up machine, tucked beside a large rock.
- Peacekeeper Mk1 — in the Nyxara Entrance, on the north side just past the doorway.
- VS Recon — on the south wall of the Nyxara Sanctuary, a few steps past the Arsenal Machine.
Caltheris Entrance wall buys
Both Caltheris wall buys sit in the same entrance area, east of the Nexus Forge. The M10 Breacher shotgun is the first one you’ll hit, far north of the Wisp Tea machine. Carry on through the doorway and the X9 Maverick assault rifle is mounted on the south wall of the hallway.
Dravakar wall buy locations
Dravakar’s three weapons are spread from the passage up to the sanctuary at the back. The Dravec 45 sits on top of a ledge above the Dravakar Passage, north-east of the Nexus Forge. The M34 Novaline is inside the Dravakar Sanctuary, on the left-hand wall of the room.
The AK-27 is the awkward one. It’s on the second floor of the Dravakar Main Chamber, over on the south side, and you have to get up there yourself. Wall-jump onto the platform from either the north or south side, or grapple straight up with the Void Claw.
Veytharion wall buy locations
Veytharion mirrors Dravakar with one weapon per zone. The M8A1 marksman rifle is on a platform in the Veytharion Passage, just short of the Vulture Aid machine. The Akita shotgun is inside the Veytharion Main Chamber, on the wall in the top-left corner of the room. The Shadow SK sniper is in the Veytharion Sanctuary, right beside the Crafting Bench.
Floating island wall buys: Spira, Ruinas, and Aranea Insula
Four wall buys hang out on the floating islands, and each island doubles as a perk stop, which makes the trips worth it.
| Island | Weapon(s) | Landmark |
|---|---|---|
| Spira Insula | DS20 Mirage | Between Nyxara and Veytharion Sanctuary; Jugger-Nog machine |
| Ruinas Insula | M15 MOD 0 | Between Dravakar and Caltheris Main Chambers; PHD Flopper |
| Aranea Insula | XM325, XR3-ION | Far north of the map; Widow’s Wine |
On Aranea Insula, the XM325 and the XR3-ION are split up. The sniper is on the south side of the island, so sweep the whole thing rather than buying the first gun you see.
Armor Vest wall buy locations
Level II and III Armor Vests are sold off the wall in four places, and all of them are in the outer regions rather than the hub. You’ll find them in the Nyxara Sanctuary, the Caltheris Main Chamber, the Dravakar Sanctuary, and the Veytharion Sanctuary.
Note: because there’s no vest on the Nexus Forge platform itself, plan your armor top-ups around whichever temple you’re heading into next.
If a wall buy isn’t showing up, it’s almost always an access problem rather than a missing spawn. The Nexus Core stays shut until the central platform drops during the Pack-a-Punch quest, and the AK-27’s platform simply can’t be reached from the ground floor. Everything else is a matter of opening the right doors and walking the map.
