Four players can walk the story together in TimeSplitters: Future Perfect. Free Radical closed the trilogy in 2005, adding that cooperative campaign and console online play to Cortez's time war.
A past mission and a future mission still share one sergeant, and the tools include a split-screen editor for people who never touch the plot. Online matches brought the same bots-and-costumes chaos to a wire instead of only a couch.
The second game had the map maker and the best reputation. Future Perfect is the one that lets friends share the campaign and, for the first time in the trilogy, take the match online.
