TimeSplitters: Future Perfect

The Arcade and Challenge modes both allow the player to unlock new characters, weapons, and new locations for Arcade (excluding league) that the player can then use in the game's mapmaker feature. The player can complete various missions and league challenges to receive awards, new characters and medals. Once the player completes a mission the game automatically saves progress. In challenges and Arcade Leagues the player earns awards. Bronze, silver, gold, and platinum medals can be acquired.

After the original TimeSplitters, Free Radical Design decided to include a level creator in the TimeSplitters series. It includes tiles, character spawns, items for specific game-modes (such as a briefcase in "capture the bag" game mode) as well as the option to change the lighting and also add pre-determined "bot sets", that is a group of up to ten characters to regularly appear on the map. The same goes for weapon sets.

The game begins in 2401 when the protagonist, Sergeant Cortez, a space marine in a futuristic military force, is leaving the space station that he destroyed at the end of TimeSplitters 2. His ship crash-lands on the future Earth, and two fellow marines greet him. Sergeant Cortez follows his squad of marines through the valley and battles unknown masked figures and TimeSplitters. After arriving at HQ, Cortez is tasked with following signatures in the past that were created by time travel and thought to be caused by the TimeSplitters. He goes on a mission to go back in time to find a way to stop the TimeSplitters race from being created, with the help of Anya, The General's Chief Science Officer.

Using his Temporal Uplink, a device connected to the Time Machine, both of which Anya has invented, Cortez travels to the small Scottish island of Urnsay in the year 1924. There, he meets a man named Captain Ash, who seeks Cortez's help. After raiding a castle with Captain Ash, Cortez confronts an unknown man with a high concentration of Time Crystals, who then escapes with his own time machine. Cortez then travels to 1969 to stop Khallos (whom Cortez thinks is the time traveler) with the help of hippie secret agent Harry Tipper, to rescue his girlfriend, Kitten Celeste. After defeating Khallos, Anya reveals to Cortez through the walkie-talkie on his Temporal Uplink that a mansion in Connecticut had burned down in the 1990s, leaving behind residue of Time Crystal energy.

The game was announced in May 2004. It was developed by a team of about 40 people.

The original Xbox version of TimeSplitters: Future Perfect was made backwards compatible on Xbox One and Xbox Series X/S on November 15, 2021.

TimeSplitters: Future Perfect received "generally favorable" reviews from critics, according to review aggregator website Metacritic. It won an "IGN Best of 2005" award for "Best First-Person Shooter"
