So this is a continuation of the mod made by one Gabriel Gorgutz forever ago, it has been seemingly dropped without any support and has obtained a lot of bugs and a lot of CTDs, I've made updates to the mod which reduce these issues as well as include the Tau and several balance changes, though the gameplay is still very similar to what was featured by Maestro Casts on YouTube a few years ago. If Gabriel has any issue with me uploading this, get in touch, I will be more than happy to take this mod down if he asks me to, but I hope that he and others will enjoy the work that I've put into his original project to make the mod work again with the current build of Retribution.
Part of the new update/hotfix and the main patch, a bunch of new skins for various chapters, warbands, craftworlds, regiments and much more. Every faction has at least a few default army painter skins which give the units a different appearance, the most notable being Chaos & Loyalist Space Marines, but every faction has a few schemes which give different models.
