FinalSun is a semi-official map editor for Tiberian Sun and Firestorm, capable of creating multiplayer and singleplayer maps, along with special triggers and INI editing. To hide its complexity to new users, it also offers a simplified beginner mode. Integration with SunEdit 2k allows the addition of new units to the map or modify existing ones. The successor, FinalAlert, is mostly identical, adapted to Red Alert 2 and Yuri's Revenge, inheriting some residual coding like tunnel support. A derived version was made for the Twisted Insurrection mod, called FinalTI.
