About TimeShift:
Set in the near future, TimeShift from Saber Interactive will take the first-person genre to an entirely different dimension marked by erratic time and unrelenting action. The unprecedented technology behind TimeShift will allow gamers, for the first time, the ability to slow, stop and reverse the flow of time while remaining completely unaffected. Set in an engrossing storyline, gamers must learn to master this new skill while navigating through the new universe and ultimately complete the adventure. Using Saber Interactive’s proprietary Saber3D Engine, the story will progress through virtual environments of cinematic quality, and the game’s sophisticated AI will challenge gamers to think creatively on how to use their new powers.
