I have re-release the 3 mission demo of Time of Change. You can download it by clicking here. It contains a five mission campaign containing 3 playable missions and two cutscene, all to be found in 'Time of Change'. Also present is the mission 'Vasudan Gauntlet' from Descent/Conflict:FreeSpace and the authentic sounds for each player usable weapon (although to get the full effect you have to play the Gauntlet).
