From The TimeSplitters Wiki

The first League Match in this Series is a joke on the N64 game, "Turok: Dinosaur Hunter".

Briefing

Aztec Warrior just loves to hunt Dinosaurs! The Aztec Priest has tried to convince him otherwise by explaining all of the ethical and ecological reasons which make it a morally questionable activity. Aztec Warrior ignores him, he says the Priest's just a cerebral bore...

Strategy

Since you only have a Crossbow for a weapon, there's really no need to list the weapons in this match. The best place to hide is at the other side of the bridge, inside the cave near the gearworks. Stand in a place where the Dinos can't see you until you do, then blast any that come. Standing right at the end of the bridge is a bad idea, since they can shoot you with better accuracy than you. This strategy should get you a Silver atleast.
