Operation: TREBUCHET First Contact

Article 2 Studios

Operation: TREBUCHET First Contact is an expansion for the Operation: TREBUCHET modification for ArmA 3. It will be developed separate from OPTRE and will not affect the development speed or process of OPTRE. Unfortunately, it will not be developed as quickly or frequently as OPTRE, as it is mainly a side project and fan service. However, we will do what we can to fix glaring bugs and issues and add new content as it it is ready.


To install Operation: TREBUCHET First Contact you should use modfolders to keep it seperate from the official game content to prevent issues.
With Arma 3 you can use different ways to set up your modfolders to use custom content you have downloaded.
Please visit the Arma 3 Mod install instructions page for more information about using custom mods and addons in Arma 3.
