Treason originally started as a Counter-Strike: Condition Zero server mod in 2016, heavily based on the TTT/Murder mode from Garry’s Mod. After a year of wasting too much time mapping and perfecting the Treason gamemode on the CS:CZ server, Klaus realized that the shooting and weapon mechanics of the old GoldSource engine were a bit too hardcore for the casual FPS experience. Additionally, he would always need to convince people to get CS:CZ to play his silly gamemode.

He began exploring other engines, including Unity and Godot, to make the whole gamemode as a standalone game, with the focus on weapons that are easy to learn but hard to master.

After years of development, Treason was rebuilt on the Source engine.

We believe this game should always be available for everyone to enjoy, for free. If you’d like to support us, you can find ways to do so on our Discord server.
