Rad-Therapy (FreeHL)

Clean-room reimplementation of Valve's Half-Life: Deathmatch and Half-Life (Experimental, this means Singleplayer is NOT complete).

Similar to Tactical Retreat (FreeCS), this aims to recreate the feeling of the original game. It's designed to work with the content from the Steam & CD version of the game. There may be version mismatches between the different versions of Half-Life that you play. So you have to make sure you're running similar versions when hosting a game for someone.

Netplay improvements, such as prediction of both player physics and weapon-logic are present.

This is 100% original code, feel free to audit however you wish. No proprietary SDKs have been looked at or taken apart, unlike similar projects.

Installing

To run it, all you need is FTEQW and the latest release .pk3 file, which you save into Half-Life/valve/. That's about it. You can install updates through the Configuration > Updates menu.

Building

Clone the repository into the Nuclide-SDK and build it:

$ git clone https://code.idtech.space/fn/valve valve
$ make game GAME=valve

You can also issue make inside valve/src/, but it won't build an entities.def file for use in Radiant (level editor family).

Notes

The engine should automatically detect Half-Life when placed within the game directory, however you may need to pass -halflife just in case you have one massive directory with multiple FTE-supported games in it for example.

You can also launch mods like this: fteqw -halflife -game cstrike Useful for development, so you don't have to use the Custom Game menu.
