Previous pilot abilities were only activated in the pilot's preferred Mech, due to the familiarity with the machine. In GenCon 2007 WizKids announced the production of a Solaris VII champions set, coinciding with the six Players who had won the Solaris VII Open Worlds Event hosted that year. However, due to issues in production, the Mechwarrior line was put on permanent hold status, and the Solaris VII Champion set was never produced. WizKids did however, create a set of custom mechs based on existing sculpts for the six Champions, they are the only known Solaris VII Champion mechs produced, but did not come with pilot cards. In 2003, WizKids produced a special DropShip playset. Sold only at conventions and through special promotions, the "Aurora" DropShip is a massive unit that has five cannon turrets and four bays for repairing units. The playset also has special rules. The "MechWarrior: Dark Age" game also shares its name with its companion series of novels. As of July 2008 there are 30 novels in the "MechWarrior: Dark Age series".
