In single-player, the player advances through a series of scenarios by playing missions in a campaign. Every mission initializes with a briefing stage, allowing the player to choose their equipment, coordinate their attacks, and develop the plot. Throughout each mission the player directly controls one team member, and can take control of any living operative. However, any casualties cannot be used in future missions unless the mission is reset. In multiplayer, the game pits two teams of players against each other in order to complete objectives depending on the game mode.
