Operation TREBUCHET First Contact


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.

"Wont effect OPTRE dev, will be updated slower" Looks at all the content First Contact has recieved. Looks at neglected Innies.. uh huh sureeee

Had this on a dedicated server, and my spartan unit I spawned into didn't have the option to activate the suit. Is there something I'm missing? It works fine in local single/multiplayer in the editor, but not on a dedi.
