The indie RTS game, Diplomacy is not an Option, will be adding new units and buildings in its latest update. Along with the free update, some rebalancing of the game has been implemented that makes it easier for players to expand their bases.
Developed and published by Door 407, Diplomacy is not an Option is a base building real time strategy game that pits a minor Lord against armies of enemies hell bent on storming his castle. Players have to strategise their options as up to 25,000 baddies swarm the field of play.
Already the game has over 100 hours worth of story to discover, as well as an endless horde mode. The latest update introduces a whole new faction of undead warriors to control and train up. The faction has a sprawling research tree of up to 64 individual techs to unearth, along with five new units.
