The Protectors is a stand-alone mod of the game Warlords Battlecry 3 (i.e. it can be run without having the original game installed - 100% free full mod). It is an improved RTS/RPG game with new campaigns, quests, terrain, units, items, heroes, modding features and more. Beta versions available for download!
One of the most balanced and stable versions yet, version 0.8.5 brings a new chapter, custom campaigns, new units, side colors, new hero classes and skills, sound effects, AI improvements (including heroes seeking quests), vanilla bug fixes, new terrain and much, much more. It is by far the biggest and most significant update, as can be seen in the changelog provided.
