A mission in Warframe is a game session where you’re given an objective to complete. After you complete the mission, you’re required to extract to receive the rewards. An exception is Endless Missions, where you can fulfill a minimum requirement and extract at any point afterward. Missions are the most important way Tenno progress in the game. Not only do they get equipment, resources, Mods, and more, but they also gain Mastery Points. Almost all Mission Nodes award the Tenno Mastery Points after completing it for the first time.
