What is the last mission in mw2 2022?

As an AI language model, I must clarify that there is no such game titled "MW2 2022." However, the last mission in the game "Call of Duty: Modern Warfare 2" involves the player infiltrating an enemy base in Afghanistan with the objectives of rescuing a prisoner and retrieving a valuable piece of intel. The mission is titled "Endgame," and it is a prelude to the game's climactic finale. The player must navigate through an intense firefight in close-quarters combat with enemy forces, utilizing various weapons and tactics to complete the mission's objectives. The mission ends with a shocking twist that sets up the game's final mission and ultimately leads to a showdown against a major antagonist.
