For characters that are similar to humans, see Humanoid
Human characters make up the bulk of the TimeSplitters characters. They vary in size and all have different traits, although most are vulnerable to fire.
Most of the Story Levels on all 3 games are based on Earth, meaning that many human characters are characters in the game. All but 3 levels (from all games) are based on Earth. The levels that do not take place on earth are Planet X (TS1), Return to Planet X (TS2) and Space Station (TS2).
