Fresh from celebrating a successful year in Early Access, Siege-survival RTS Diplomacy Is Not An Option is gearing up to march out of Early Access this November. But there's plenty of skirmishing to be done before then, including a major new content update this Spring.
A year under siege isn't to be sniffed at. Walls have been built, armies have been crushed and the peasants haven't bathed nearly enough. Today, independent studio Door 407 celebrate a year of Early Access development for their siege survival RTS Diplomacy Is Not An Option.
