Having two different gameplay routes is great because it not only provides replay value, it also gives players the chance to experience the perspective from both the protagonist Yame and antagonist Imhotep. The ultimate goal is to get to reach the end-boss of both the game and movie its based off of: The Scorpion King. Rick tends to stick to guns and explosives, while Imhotep wields blades and magic. While both characters have similar controls - their moves, inventory, and stages are unique.
From a gameplay design view, this is pretty neat. Released inthird-person action adventure game The Mummy Returns was inspired by the story of the movie of the same name.
