Cryptic Studios has released more information about Issue 9: Breakthrough for City of Heroes/Villains. Among the highlights of this issue is the new invention system.
Invention System (Heroes and Villains)
Using the highly anticipated Invention system, players acquire and collect "loot" in the form of Salvage and Invention Recipes. These are used together to invent uber-enhancements, costume pieces, and more. This creates a world of new activities, rewards and character evolution!
Auction Houses (Heroes and Villains)
Where better to buy and sell all of these new items than in the new auction houses! Wentworth's Fine Consignments have sprung up throughout Paragon City™ while the villains prefer to do their bidding alongside "black-market" trucks placed throughout the Rogue Isles™.
