The TimeSplitters series Story mode spans 548 years from 1853 to 2401, and features 32 unique levels, set in 25 different locations across the world and outer space. TimeSplitters 2 has the largest time-span, reaching to both ends of the timeline, while TimeSplitters Future Perfect spans 477 years from 1924 to 2401.
The original TimeSplitters was engineered to span exactly 100 years from 1935 to 2035, with systematic gaps between each level. It should be noted that some of the futuristic levels in the game propose unrealistic technologies and inconsistencies with the later games; this does not necessarily mean they should be considered as non-canon, or that different dates should be used (suggested dates are mentioned below). The premise of the TimeSplitters series is the altering of human history via Time Travel, so that the futuristic levels (or all levels) of the original TimeSplitters may be depicting events within an altered timeline, which is later corrected.Little Prospect, former Confederate soldier, The Colonel begins to take control of the town through fear and oppression.
