Tibercraft is a modification for Warcraft 3 which converts it to Tiberian Sun. This basically means Tiberian Sun in a three dimensional universe!

Tiberian Sun had a bad game engine. The game was too dark, and obviously by today's standards the game is outdated.
But the C&C franchise is successful because of these early games, C&C95, Red Alert, Tiberian Sun etc

The goal of PPM's newest project, Tibercraft, (or tibcraft for short) is to bring the elements that made TS such fun and bring it into the engine of a more flexible game, warcraft 3.
