A custom client launcher for Nexon's Counter-Strike: Online 2, written in C++.

Ready for this CSO2 master server.

You must allow launcher.exe in your firewall and, either port forward ports 27015 to 27020 or open your router's NAT, in order to play with others.

If you host a room match, your IP will be known to other clients.

If you join a host's room match, your IP will be known to the host.

This might be avoidable in the future once a dedicated server launcher is developed.

• BitTorrent, magnet link: magnet:?xt=urn:btih:7BUJS77RR2AYAXCFPF7TSSSRF2NWUOU6

Tested with Visual Studio 2017. Support for other compilers is unknown.

cso2-launcher uses CMake to generate project files and to build itself.

You can build it through CMake or generate its project files.

For example: to generate Visual Studio 2017 project files, open a terminal instance in the project's directory and run

# in powershell or in standard Windows cmd
cmake -G "Visual Studio 15 2017" ./

Or use the cmake-gui tool bundled with CMake for a more user friendly experience.

Once successfully generated, you can open CSO2Launcher.sln and build the project in your preferred configuration.

If built successfully, you will find the launcher inside out/bin/Win32/[your configuration].
