HL2Quest 1.01 — SideQuest edition

Separate distribution of HL2Quest 1.01 for Meta Quest 3 and Quest 3S.

• Android package: com.alferiko.hl2quest.sidequest.
• Headset app name: HL2Quest (SideQuest).
• Version: 1.01, Android version code 1010.
• Automatic and manual in-app APK updates are disabled. Update this edition through SideQuest.
• APK installation permission, the legacy updater service and update-file provider are removed.
• Engine libraries, game resources and VR resource archives are unchanged from the verified public 1.01 release. Steam game downloads remain available in the launcher.

Install and switch editions

Install hl2quest-sidequest-1.01.apk using SideQuest or adb install -r hl2quest-sidequest-1.01.apk.

This installs alongside the regular GitHub edition; it does not replace it. Both editions can use /sdcard/srceng for game data and saves. Launcher preferences and Android permissions are separate. Back up saves before switching, and do not run both apps or their game-data installers concurrently. Do not uninstall or clear the regular app as part of installing this edition. Future SideQuest updates should be installed over the SideQuest edition.

You must own the selected games on Steam. Download them through the headset launcher, or use the optional PC cache builder from the main release. Current Anniversary game content is supported; no Legacy downgrade is required.

Setup, controls and log collection · Report an issue

This release is kept separate and is not marked Latest, so the regular edition's updater continues to use the original public APK.

Validation

Verified APK signing, 16 KiB alignment, ZIP integrity and unchanged engine/resource payloads. Installed alongside the regular edition on Quest 3. The launcher started; Half-Life 2 with Vulkan and GLES and Portal 2 with Vulkan loaded their initial maps and remained running for 30 seconds. An initial HL2 Vulkan PID probe was inconclusive; an unchanged repeat succeeded. These are basic startup checks, not full campaign or performance certification. Original APK, saves and VPK/BSP cache records were unchanged; original configs were restored after testing.
