Xash3D FWGS

Ready to run the original Half-Life engine on your Android phone?

Xash3D FWGS is a fully functional, open-source engine reimplementation designed to bring GoldSrc-based games—including Half-Life, Counter-Strike 1.6, and many classic mods—directly to your mobile device. Developed by Flying With Gauss, this engine provides near-native compatibility with the original PC binaries, letting you load your own legally owned game files and play with full mouse and touch controls.

Core engine capabilities

• Full GoldSrc compatibility – Loads original Half-Life, Opposing Force, Blue Shift, Counter-Strike 1.6, and hundreds of community mods without emulation.
• Touch input system – Customizable on-screen buttons, joystick, and gesture mapping. Supports simultaneous keyboard+mouse via USB/Bluetooth.
• High frame rate rendering – OpenGL ES 2.0/3.0 backend with dynamic lighting, particle effects, and widescreen aspect ratios.
• Save & load states – Full savegame support identical to PC. Quicksave and quickload mapped to touch gestures.
• Multiplayer support – Connect to dedicated servers or host local LAN games over Wi-Fi. Peer-to-peer voice chat via external plugins.
• Mod loader – Drag-and-drop .gcf or .vpk packages into the game directory. Automatic detection of installed mod folders.

Key advantages over other solutions

• No emulation overhead – engine runs natively on ARM, delivering 60+ FPS on devices with SD 660 or newer.
• Zero ads, no in-app purchases – fully free and open-source. No time limits or feature gates.
• Active community updates – regular patches for Android 5.0 through Android 14, including scoped storage compliance.
