Western Region After escaping from the White House, the President begins his counter-offensive on the West Coast. He flees to an underground hangar where Air Force One is waiting to fly him out of the Capitol from beneath the Reflecting Pool as it opens up. This is the opening stage of the game where Michael Wilson escapes the coup d'etat forces in Metal Wolf. The player is also able to revisit previous stages and grind back through them in order to rescue any hostages that were missed, discover new weapons, or earn more money that can be used to build new ones during the intermission menu. After finishing certain areas, more missions become available as Michael Wilson moves across the nation from West to East, allowing the player to choose where to go next. The game requires the player to journey to several different stages in order to take part in specific missions assigned to each one. In between each mission in addition to purchasing new weapons, the player can also pick which weapons they would like to go into battle with and reconfigure Metal Wolf's loadout. Missions that have been successfully completed can be repeated to grind for more money or improve the player's performance for additional bonuses. At the end of each mission, the player's performance is scored against several variables such as total destruction caused to enemies killed which goes toward how much cash the player will have available to spend on weapon development in order to expand their arsenal.
As the President, the player is given a set of objectives that typically consist of destroying all enemies, destroying specific objectives such as a building, or fighting a boss battle. Weapon crates conceal ammo for the various weapons and can be found scattered throughout each area along with hostages that can be freed for bonuses.
