ER Apex: Octane

Play ELDEN RING as Octane from Apex Legends. An offline fan mod: Apex's movement, first-person guns, abilities and HUD in the Lands Between.

Based on umiiii/er-apex by umi (MIT). This build is MegaWeed/er-apex, a fork with more guns, abilities and fixes. The architecture comes from er-mario.

Recommended: install from GitHub with an AI agent

If you can, have an AI coding agent (Claude Code, Codex, Cursor...) set the mod up on your PC straight from MegaWeed/er-apex by following its README. Fixes land there first, so you get them as soon as they are pushed, without waiting for a new Melty release.

What you get

• Apex movement: sprint, slide, slide-jump, Octane's jump pad with its double jump; stairs and ledges stepped like Apex.
• Seven guns with Apex's own first-person models, animations, and sounds: Wingman, R-99, R-301, VK-47 Flatline, Sentinel (homing rounds), Mastiff, Charge Rifle. Weapon wheel on Tab, inspect on 5, a holstered mode with Wraith's kunai.
• Octane's stim (Q) and jump pad (Z), shield battery (4), frag grenade (G), Pathfinder's grapple on the wheel.
• Apex's HUD: health and shield, ammo, kill feed, damage numbers, hit markers, a kill-streak rank badge.
• F5 switches back to your own Tarnished and again to Octane.

Before you start

• You need Apex Legends installed (its files are only read) and Build Tools for Visual Studio 2022 with "Desktop development with C++" (free: https://visualstudio.microsoft.com/visual-cpp-build-tools/). They are used once, on the first start, to build the Apex file reader.
• The first start takes about 70 minutes and about 20 GB: Octane's models, sounds, and HUD are made on your PC from your own Apex Legends install, in a console window. Later starts go straight to the game.
• No game files are shipped. Nothing from Apex Legends or ELDEN RING is in this download.
• Offline only. The bundled me3 starts the game offline with Easy Anti-Cheat off, on its own save (ER0000_apex.sl2, a copy of your normal save): your normal save is never touched.
• Shadow of the Erdtree (the DLC) has not been tested. Its areas, enemies, and bosses may not work with the mod.
• Custom skins and models (the R-99 Cutting Edge, the Flatline Teal Zeal, your own textures) are not in this build: install them yourself as the GitHub README describes. You provide the textures yourself.

Known bugs

1. The waterwheel at the Academy of Raya Lucaria can only be used as your own character: press F5, use it, press F5 again.
2. In invasion contracts, the Sentinel's shots will damage yourself. 3.https://github.com/MegaWeed/er-apex/issues u can report bugs here
