Operation: TREBUCHET

Operation: TREBUCHET (OPTRE) was the last major UNSC offensive against the human insurrection before the first contact with the Covenant empire. Our mod will focus on the struggles of the common soldier rather than the elite spartan warriors, allowing you to experience the Halo universe from a new, brutal perspective. OPTRE is a total modification with the intent to bring the popular Halo Universe into a more realistic setting by introducing it into Arma 3.





If you want to get in contact with us or the OPTRE community in general we highly recommend joining our Discord[discord.gg] or one of the communication channels linked on the right.
