Vor wenigen Minuten hat Relic auf ihrer Community Seite das Script für Mods veröffentlicht. Alles weitere findet ihr unter der Quellenangabe. Viel spass beim modden. 
What is SCAR? It stands for Scripting at Relic and is a term we use when talking about the lua-based scripting language that is used to create our scenarios and other game rules. Today we’re making our SCAR documentation for Dawn of War II available for fans that are interested in modifying the game. Combined with our recently released World Builder, this documentation gives fans that are willing to put in some time and effort the tools to modify the game in some very significant ways or create something quite new.
As part of releasing the DOW II SCAR documentation, we have also opened a Modding Forum here on our community site to give players a place to share their ideas and experience with SCAR and modifying the game. We’re very excited to see what the modding community comes up with!
Vielleicht findet sich ja der ein oder andere hier im Forum, der ein kleines Einsteiger how-to schreibt was man dann hier anhängen könnte. Danke.
