From The TimeSplitters Wiki

Escort is one of the arcade modes in the original Timesplitters game. The chemical plant level, the spaceways level, the Streets level and the docks level, where the only levels to feature this game mode

Objective

The player had to protect a selected bot from damage by the other team. The player could only be on the defenders (blue) team, never the attackers (red).

Controversy

This is among the harder of play options in TS1, such as Last Stand. What makes it so hard is the fact that players are very sensitive to damage including the escortee, unlike in the sequel, TimeSplitters 2. This, like Last Stand, has not been featured in any other TS games since TS1.
