Unfortunately, Zero is no longer a member of the development team for Operation: TREBUCHET, or Article 2 Studios as a whole for that matter. He has informed us that he wishes to leave the project and seeks to remove his assets wholly from the mod. It is our understanding that this occurred due to a conflict of interest between his working with our team and the developers of the Sins of the Prophets mod for Sins of a Solar Empire, whom collaborated with him on and contributed a number of assets to his own mod, Operation: HOMEFRONT. These developers are working on their own ArmA 3 mod, also set in the Halo universe, and presumably wish to use these assets in their own mod. They threatened Zero with revocation of his right to use some of their assets in Operation: HOMEFRONT if he did not comply.

Please note:
Upon further investigation alongside the SOTP team, it has been determined that Zero was not honest with us about the reasoning behind his departure and SOTP's involvement in it. We would like to apologize for this confusion. We still have every intent to remove his assets, but wanted to be forthcoming with accurate info on the situation.

So, what does this all mean for you, the player? Well, best case scenario, almost nothing major. We are currently working to recreate almost every asset we will lose with this departure and have made good progress on most of them, but still have some to go. We will try to provide updates on these asset replacements along with standard new content. Our goal is to minimize the impact this will have on development of new content, but we will unfortunately have to make some short-term sacrifices to fill the gaps left behind.

Most of the assets have already been assigned to developers or are already being worked on, with some even being complete as of now. Some of them, unfortunately will not be as high of a priority for us and we will have to evaluate their overall worth relative to the general gameplay of the mod. Two examples thus far are the Longsword and the Frigates. It is unlikely we will recreate these assets at this point in time simply due to the fact that they don't provide a significant addition to the overall gameplay we feel and the amount of effort required for their proper implementation is not justified by the benefit. However, for the many undoubtedly disappointed in this news, know that we are actively working on alternatives to both of these assets that should fit the gameplay and scope of ArmA better, while still providing the same level of quality you've come to expect from us.

While this is a disappointing setback for us, we are determined to provide even better content and quality, all we ask is a little patience and understanding as we work to overcome this.
For specifics, the following is a list of all assets that were created by Zero and will need to be replaced:

MA5A, MA5B, and MA5C Assault Rifles
M7 SMG
M6G and M6C Handguns
M41 SSR Rocket Launcher
M9 Frag and M2 Smoke Grenades
Emergency Flare
GA-TL1 Longsword
Charon and Paris-Class Frigates and Interior Objects
Traffic Cone
Portable Generator
Resupply Pod

(Precise classnames and object titles will provided in the near future to help everyone try to adjust accordingly)
