PrimedGun Echoes (Metroid Prime 2 VR)

Overview

PrimedGun Echoes is Metroid Prime 2: Echoes in native VR on standalone Meta Quest. It is not an emulator: it carries the VR layer of PrimedGun v2 onto Echoes Unbound, Odrannnn's native port built from the PrimeDecomp decompilation. It keeps the controls of the original PrimedGun.

Install type: APK + your own disc image.

Highlights (v1.0.0-alpha.4):

• 6DOF arm cannon tracking for aiming, grapple and lock-on, with left-handed play.
• Room-scale movement, snap or smooth turning, one-click height calibration and an adjustable cannon position.
• Beam wheel and visor gestures, a 3D map and the pause screens in the headset.
• In-headset settings for controls, calibration and graphics, plus Setup > Check for updates inside the app.

[!WARNING] Alpha. Expect rough edges and keep normal in-game saves. The Seeker Missile multi-lock, the Screw Attack camera and the turrets still use the original pad behaviour, and local multiplayer does not work in VR. Tested on Quest 3 only.

[!NOTE] No game data is included. You need your own, legally owned disc image of Metroid Prime 2: Echoes. USA (G2ME01) is the tested release; PAL (G2MP01) and Metroid Prime Trilogy are experimental. Fan project, not affiliated with Nintendo.

Prerequisites

1. Meta Quest 3 with Developer Mode enabled. The APK is about 31 MB.
2. Your Echoes disc image: .iso, .nkit.iso, .gcm, .rvz, .wia, .ciso or .wbfs.

adb install -r PrimedGunEchoes-v1.0.0-alpha.4-Quest.apk

The checksum is in SHA256SUMS.txt on the release page.

2. Put the disc image on the headset

Copy the image to any folder you can reach, for example Download:

adb push "Metroid Prime 2 - Echoes (USA).iso" /sdcard/Download/
