Locations
In MegaMan X: Corrupted, almost all areas are connected through a contiguous world map after beginning the main game.
Intro Stages
These are the intro stages for X and Zero. These stages will not be accessible (at least in the same form) after being beaten.
Island Regions
These are the neutral areas that connect to each of the main stages. Certain paths will be blocked off and require certain Mavericks to be defeated to progress.
Main Maverick Stages
Each of these areas act as a traditional "stage," each with their own gimmicks, theme songs, minibosses, and Maverick. After reaching the beginning of each one, as well as at the middle point of each stage, you will activate a Transfer Station that will allow fast travel between other Transfer Stations, including the one at the Hunter Outpost.
Event Stages
These areas are plot related.
