FreeCS

As seen on phoronix.com

Clean-room reimplementation of Counter-Strike 1.5 (mod-version).

Aiming for a stable reimagining of the original mod in QuakeC. Not aiming for accuracy, but for a smooth, exploit and bug-free experience over the Internet.

Done in my freetime for countless reasons, but most important to me: to learn everything there is to know about one of my favorite games.

This is all 100% new, original code written by good old trial and error. Differences exist and features are slowly being implemented one by one. This allows the code to be fully free and unencumbered, unlike similar projects.

Featuring proper weapon prediction to enable stress-free netplay.

The engine you want to use to run this is FTEQW (https://www.fteqw.org), which is a project unrelated to this. It just happens to support the file-formats FreeHL needs.

Features and Improvements

  • Native support for Windows/Mac/Linux/BSD and wherever else FTEQW runs on
  • Better support for higher display modes and aspect ratios
  • Much easier modding by having the entire logic be in modern QuakeC
  • Netcode that's always improving and more advanced prediction
  • Open-source code for transparent modding
  • Very permissive license (ISC/BSD)

Installation

Grab the latest binary release, extract and put an FTEQW engine binary (for your platform) into the same folder as the default.fmf and readme file. Get FTEQW here: https://www.fteqw.org/

Run the engine and when in-game download the needed content, or optionally merge your own HL + CS 1.5 installation.

Building

Make sure you've cloned the FreeHL repo (external) into the Nuclide-SDK.

Clone the repository into the Nuclide-SDK:

git clone REPOURL cstrike

then either run Nuclide's ./build_game.sh shell script, or issue 'make' inside ./cstrike/src!

Obviously make sure that Nuclide has fteqw and fteqcc set-up for building.
