The Protectors of Etheria 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 game). It is an improved RTS/RPG game with new campaigns, quests, terrain, units, items, heroes, modding features and more. Beta versions available for download!
Orcs can boost their resources by constructing Salvage Pits! Each pit increases the % amount of resources gained from killing units and destroying buildings (based on the resource value of the killed unit or destroyed building. You can build a maximum of 3 pits).
A delightfully ruthless idea, very fitting for orcs.
Awsome idea, very Orky!
It makes sense that a giant Horde would have vast inventories of plunder, like the Huns or the Mongols did, and even often use it as currency.
Besides, everyone loves plundering Orcs, it is their brand!
