This is the code tree for TF2 Panda. It contains all of the game code and configuration files. It is mostly Python, with some of the client-side prediction system being written in C++ as a performance optimization.
The game is still a work-in-progress.
In order for gameplay mechanics to be as accurate as possible, a lot of the code from original TF2 was used as reference.
The game cannot be run from this repository as-is -- it must be built against the rest of the engine using its build system, and integrated into the development environment. The engine is a collection of separate repositories, which are available here. Instructions for setting up a developer build of the game are available in the Wiki.
The assets for the game are stored in a separate repository: tfmodels
