Challenge

Challenges are Competitive Missions against AI-controlled foes which aim to simulate and train PvP combat.

They are not Arenas, as no actual PvP combat takes place, although they make use of the same maps as those that are used in the PvP arena system.

Challenges have a distinct icon on the game map, which - at a glance - looks like a mission icon.

Currently there are only two challenges in the game: More may be added later, or as part of Guild Wars: Factions.
 * Zaishen Challenge
 * Zaishen Elite Challenge
