The Treasures of Aht Urhgan expansion disc will introduce an entirely new way to play FINAL FANTASY XI--“Assault” missions!
The FINAL FANTASY XI development team created the "Assault" system to provide a means of casual enjoyment for high-level players--the main target audience of the Treasures of Aht Urhgan expansion disc. Assault allows for parties of three to six members to enjoy gameplay that does not last a long period of time and requires little recruitment effort. Players can choose the location, decide whether or not to impose a level restriction, and select the type of Assault mission to fit with their objectives and party organization.
Players who often participate in Assault missions will earn "Assault Points" credits, which can be traded for items in the various Assault locations. In addition, players who succeed in an Assault mission have the possibility of obtaining a mysterious item. After receiving an appraisal in town, the mysterious item will then be displayed as a normal item.
Repeat success in Assault will also raise your mercenary rank, which will even further increase the number and variety of available Assault missions!
