The HoloCom (HC) was a supplementary gameplay application utilized in the early years of the Star Wars Combine. In April 2000, the HoloCom and the Combine Commander (CCom) were replaced by ICIS, which was subsequently replaced by the Darkness interface in December 2003.
The HoloCom was one of two programs used by the early Star Wars Combine simulation. The HoloCom client allowed the player to travel through space, to move around on the surface of planets, to visit buildings and to role-play with other Combine players. The HoloCom also featured an Auto-Refresh function, Hidden Structures, Secret Rooms, Personal Messages and different travel speeds.
