=== Westopolis ===
Like the original, it is the first stage of the game. Westopolis is one of the districts in Central City that is under attack by the Black Arms.

This stage is found in the interstate highway areas of Central City. It is just like the originally named Lethal Highway stage only that it adds a few elements from Radical Highway with the red bridges.
