Warpath: Jurassic Park Codes and Unlockables (PSX)

Warpath: Jurassic Park is a video game released on the PlayStation console in 1999. It is a spin-off of the movies Jurassic Park and The Lost World: Jurassic Park, in turn adapted from bestselling novels by Michael Crichton. It was developed by DreamWorks Interactive and also worked along with Black Ops Entertainment. Warpath is a fighting game similar to Tekken; the player can choose a dinosaur to fight with against other dinosaurs. Each dinosaur has its own array of fighting techniques and style. Various arenas based on scenes from the movies are shown in the game, such as the T.rex enclosure from Jurassic Park and the S.S. Venture deck from The Lost World.

Some arenas feature destructible objects such as boxes, which will hurt the dinosaurs when they break them. Optionally, various edible creatures (goats, dogs, humans and Compsognathus) will scurry across the arena, partially replenishing lost health when eaten or killed by one of the fighters (feature from Primal Rage). The game features a variety of modes similar to other fighting games like Tekken. The main mode is Arcade.

In this mode the player must face each dinosaur in the game through 9 fights. This mode has a time limit and round limit, though can be changed with the options. The arcade mode can also be used to unlock new playable dinosaurs until there are no more to unlock. (Wikipedia)
