About

A native VR port of No Gravity, the arcade space combat game by realtech VR (1997), later released as open source under the GPL. Fight across five worlds against fighters, capital ships and space stations, with missions, wingmen and upgrades between flights.

You fly in head-tracked stereo 3D: look around while ships, planets and explosions sit at real depth, with the HUD and crosshair fixed in front of you. Menus float on a large screen. The whole game is inside the APK, so there is nothing else to copy.

PICO support is brand new and not tested on PICO hardware yet: reports are very welcome. One APK covers both makes.

Features

  • Head-tracked stereo 3D in flight at 72 Hz, 2400 x 2400 per eye with 4x anti-aliasing
  • HUD and crosshair lined up with your guns; hit and explosion flashes fill your whole view
  • Touch controllers as the flight stick: analog pitch, turn and roll, plus a throttle lever
  • Menus on a large floating screen, on-screen keyboard for the pilot name
  • Complete game inside the APK
  • Runs on PICO 4 / Neo 3 too, from the same APK (untested)

Manual

Installation

  1. Enable developer mode on your headset.
  2. Download the APK below.
  3. Sideload it with SideQuest or adb install -r NoGravity-VR-v0.1.1-beta.apk. SideQuest is a Quest tool, so on PICO use adb or whichever sideloader you already use.
  4. Launch No Gravity VR from Library → Unknown Sources (on PICO: Library). The first start takes a few seconds longer while the game data is unpacked.

Good to know

  • This is the first public beta, tested on Quest 3. Please report problems on GitHub.
  • To quit, press the Menu button in the main menu and answer Yes: the game closes and you're back in the Quest home.
  • Resolution and anti-aliasing can be lowered without reinstalling: put NGQ_EYE_SIZE=2000 or NGQ_MSAA=0 lines in /sdcard/Android/data/com.bilko.nogravityvr/files/env.txt.
  • The APK is signed with a debug key (sideload only).
  • The port's code is GPL-3.0; the No Gravity game data is GPL-2.0.
  • PICO needs PICO OS 5.9.0 or newer. The PICO build is untested: if it does not start, or the controllers do nothing, please open an issue on GitHub. adb logcat -s NoGravityVR:* shows how far it gets.

Button names are those of the Meta Quest controllers; PICO controllers use the same layout. Flight buttons can be changed in the game's joystick options. Pilot name keyboard: stick moves, A types, B deletes, X adds a space, Y is OK.

Download

Install from your browser

One click over USB, for Meta Quest and PICO: no SideQuest needed. Works in Chrome or Edge on a PC, Mac or Android phone.

The installer needs JavaScript. Use the manual download below.

First time? Before you start
  1. Turn on developer mode. Quest: Meta Horizon app on your phone → Devices → your headset → Headset settings → Developer mode. PICO: Settings → General → About → tap Software version 7 times, then Settings → Developer → turn on USB debugging.
  2. Connect the headset to this computer with a USB cable that carries data (not a charge-only cable).
  3. Close SideQuest and Meta Quest Developer Hub. If you use adb, run adb kill-server first: only one program can talk to the headset at a time.
  4. Windows: if the headset doesn't show up in the list, install the Meta Quest ADB driver.
  5. After pressing Connect, put on the headset and allow USB debugging for this computer.
