Cortez hops centuries in TimeSplitters 2, and each mission is a different decade's gunfight. Free Radical's 2002 shooter is remembered for those time-hopping assignments, a map maker, and multiplayer that outlasted the story for a lot of households.
A Western street, a sci-fi lab, and a 1920s nightclub can sit on the same disc because the plot is a chase through time. The arcade league and the challenge rooms train the tricks the story missions then demand.
The map maker lets a player place bots, weapons, and doors, which is why custom nights lasted longer than the campaign. Free Radical's sequel is the one people mean when they talk about the series' editor and its costume box.
