Mod series Kane's Return for Tiberian Sun, originally released at kyberia.sk webpage. Presently not being developed any more, but already giving quite a lot of new units, also rebalancing the game towards more dynamic game and realistic range warfare.
Final version of the main mod, adding a lot of units including a couple of ships; the pack includes a map with a lake large enough to try them all. Otherwise it adds a few mutant units for both sides, as well as units from the campaign or previous C&C. Some of them are accessible by capturing civilian buildings.
