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. There are two ways to enter a mission. In Prophecies and Factions you have an Enter-Button in the Party-Window. In Nightfall you enter the Missions through speaking with a NPC in the Mission-Outpost.

There are five different types of missions in the game:
 * 1) Cooperative Missions
 * 2) Competitive Missions
 * 3) Challenge Missions
 * 4) Elite Missions
 * 5) 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.
