WP: "Time travel and manipulation aren't exactly uncommon themes for shooting games. Titles such as Max Payne or even Star Wars: Jedi Outcast made use of slowing time quite effectively, and other titles like Timeshift allowed players to step forward or backward in time to alter things. By and large, time travel has been centered around the player, either by speeding him up or slowing down everyone else. Singularity takes an interesting view on time travel: Instead of altering time, you alter the place of objects in time. It may not sound like much, but it has the potential to be a very interesting concept if pulled off correctly. The E3 demo gave us a brief glimpse of how this unusual concept is going to work by showing us one of Singularity's early levels."
