Resurrected VRMod — Risk of Rain 2 VR mod, unofficial build by Blowntobytes

Play Risk of Rain 2 in virtual reality with motion controls, on the current Steam version of the game.

This is an unofficial, community-maintained rebuild of DrBibop's RoR2VRMod. The original mod stopped working after the game moved to a newer Unity engine; this build ports it to that engine, switches it to OpenXR, and fixes the things that broke along the way. All credit for the mod itself goes to DrBibop and the original contributors (see Credits). Released under the same MIT license.

Installation

With r2modman / Thunderstore Mod Manager (recommended): install it from Thunderstore with the "Install with Mod Manager" button, then start the game with "Start modded". If you previously imported a pre-release zip of this mod as a local mod (or still have DrBibop's original VRMod installed), uninstall that entry first — two copies of the mod must never be installed together.

[Manual install] Install BepInEx and HookGenPatcher. Then download the Latest zip — on that page, open Assets and click Blowntobytes-Resurrected_VRMod-<version>.zip. Do not use GitHub's green "Code" button; that gives you the source code, not the mod.

Then in r2modman / Thunderstore Mod Manager: Select Settings → Profile → Import local mod → select the zip in Downloads → Import local mod and start the game with Start modded.

The first launch copies the OpenXR native files into place; if the headset stays black the very first time, simply launch again. Pick up both controllers before the title screen so the runtime wakes them.

Multiplayer

Only VR players need the mod. You can play with vanilla (non-VR) players.

Requirements

• Risk of Rain 2 (current Steam build).
• A PC VR headset with an OpenXR runtime: SteamVR (any SteamVR headset, Index, Vive, Pico/Quest via Steam Link, Virtual Desktop, ALVR), the Meta/Oculus PC runtime (Quest Link / Air Link), or Windows Mixed Reality.
• BepInExPack and HookGenPatcher (the mod manager installs these for you).

Which headsets work, and the one setting that matters

The mod does not care which headset you own — it asks Windows for whatever OpenXR runtime is currently active. So the only thing to get right is that the runtime matching your headset is the active one:

Headset	Set this as the active OpenXR runtime
Quest 2/3/Pro over Virtual Desktop	Virtual Desktop streamer → Streaming → OpenXR runtime VDXR
Quest over Link / Air Link, Rift CV1, Rift S	Oculus (Meta) PC app → Settings > General → Set Oculus as active OpenXR runtime
Valve Index, HTC Vive, Bigscreen Beyond, other SteamVR headsets	SteamVR → Settings > OpenXR → Set SteamVR as OpenXR runtime
Windows Mixed Reality, HP Reverb G2	Mixed Reality Portal / OpenXR Tools for WMR → set WMR as the runtime

Only one runtime can be active at a time, so switching headsets means flipping this setting. Controller bindings are registered for Oculus Touch, Quest Touch Pro, Valve Index, HTC Vive, HP Reverb G2, WMR and the generic KHR profile, so the button layout below applies on all of them (Index/Beyond knuckles: the "grip" is the squeeze).

Turn off "Use Desktop Game Theatre while SteamVR is active" in the game's Steam properties.

Do not turn on the old "Use Oculus mode" config option — it is a leftover from the pre-OpenXR mod and does nothing in this build.

Controls

Bindings are built in (this build does not use the SteamVR binding editor). Button names follow the Oculus/Quest layout; on Index, Vive and WMR controllers the equivalent buttons are used.

Gameplay (right-handed; turn on "Left dominant hand" in the VR settings to swap the skill buttons)

Input	Action
Left stick	Move
Right stick	Turn / look
Right trigger	Primary skill
Left trigger	Secondary skill
Left grip	Utility skill
Right grip	Special skill
A	Interact
B	Jump
X	Use equipment
Y (tap)	Pause menu
Y (hold)	Scoreboard / profile
Left stick click	Sprint (or turn on Auto Sprint in the VR settings to sprint automatically)
Right stick click	Ping

Menus — the controllers act as a gamepad, and every on-screen prompt names the button that really does it (A is A, the trigger glyph means the trigger):

Input	Action
Left stick	Move the selection
A	Confirm
B	Back / cancel
X	Ready / alternate confirm
Left trigger	Back to the survivor grid (previous page)
Right trigger	Forward to the panels on the right — expansions / DLC, artifacts (next page)
Left grip / right grip	Previous / next tab in the settings panel. Nothing anywhere else — they cannot trigger anything by accident on the character select screen
Y	Open / close the pause menu, skip the intro cutscene

On the character select screen, A picks the highlighted survivor; the Ready button then becomes the highlighted control, so press A again (or move to it with the stick) to ready up. One press never does both. Up/down on the rules panel walks Difficulty → Expansions → Artifacts; A on the Expansions or Artifacts header opens that picker.

Typing (VR keyboard): move the highlight onto any text box (game browser search and filters, host name, password, tags, the password box on a game's info panel) and press A. A keyboard appears below the menu: left stick moves over the keys, A types, X is backspace, Y is space, B closes and keeps the text, and DONE confirms the box the way Enter does. A bright amber frame always shows which menu control is selected.

Chat: click the left stick on the character select screen (or in a run while the game is paused) to open the keyboard on the chat box. B or DONE sends the message; B with nothing typed just closes it. The highlight returns to the menu afterwards.

VR settings

Open the in-game Settings and pick the VR tab (the same options are in BepInEx/config/VRMod.cfg, editable from the mod manager's Config editor). Notable options in this build:

• Auto Sprint — On by default - sprint automatically whenever you push the left stick, and re-engage on its own after anything cancels the sprint (firing a skill, taking a hit).
• Highlight chests — Chest, teleporters, shrines will have a yellow glow for easy locating.
• Item hints — On by default When pinging an item or scrolling through items in a command run, item name and info will be included on your left wrist or at the bottom of the item panel.
• Seated mode — On by default Because who wants to stand when playing this game? You can disable it to switch to standing mode but you'll have to restart the game to apply.
• Hidden item displays — items whose 3D model is hidden on your own character in VR (default: Kinetic Dampener). Comma-separated, matched by in-game name; the items still work.
• Menu selection frame / VR keyboard / VR chat (left stick click) — On by default the amber selection frame, the on-screen keyboard and the chat shortcut; each can be switched off.
• Runtime hands — per-survivor hand position/rotation offsets, aim/laser offsets, a per-survivor forearm switch (<Body>_Forearm, off for False Son), and held-weapon offsets (Operator's gun, False Son's club). Edits to these take effect within 3 seconds of saving the config file, so they can be tuned while in a run.

Known issues in this build

• Hand models are not shown inside menus (menus are navigated like a gamepad). Hands and weapons work normally in a run.
• The hands for the Seekers of the Storm and Alloyed Collective survivors are generated from the character model at runtime rather than hand-made, so they are functional rather than pretty. Their position and rotation can be tuned per survivor in the config.
• Bhaptics / Shockwave haptics suit support is still compiled in but has not been tested with this build.
• Character support from VRAPI (custom survivors with VR hands) is included unchanged and untested.

The mod's internal plugin ID is still com.DrBibop.VRMod, so other mods that depend on the VR mod or VRAPI keep working.

Building from source

The original Visual Studio project files are kept, but this build was produced with a self-contained, offline toolchain that needs only PowerShell 7 — see build-tools/README.md for the reference-assembly setup and the exact build commands. The packaged zip layout (manifest.json, README.md, CHANGELOG.md, icon.png, plugins/, patchers/) is the standard Thunderstore format.
