Mission

A mission in Guild Wars, is an expedition to perform a specific task within a closed mission area. Missions are accessed through mission outposts and are played in an enclosed explorable area. The only way to enter into a mission is to press the Enter Mission button that only appears in the Party Window in mission outposts.

There are four different types of missions in the game:
 * 1) Cooperative Missions
 * 2) Competitive Missions
 * 3) Challenge Missions
 * 4) The Zaishen Challenges

Most people exclusively mean cooperative missions when they say "mission". Also, note that some players mistakenly call quests missions and vice versa.
