The Jewels appear in the Chemical Plant level of the first game. The player's objective is to enter the Chemical Plant and find the case of stolen jewels and avoid the SWAT team patrolling the area. The jewels also appear as the BagTag/Knockout item for the Chemical Plant level, and in the Industrial tile set in Mapmaker. They take the form of a small, aluminium attache case, slightly open to reveal the jewels inside. It is available in the TimeSplitters 2 Mapmaker as a story mode pickup item.
