Right now the shelves are rather bare with just three items on sale. There are Proto Repair-Bots and Vault Tickets which grant access to the Vault instance.
The Proto Repair-Bots let players repair stuff on the move while the Vault Tickets come in singles or as stacks of five. These let you access the Vault instance which gives you the chance to earn more unique reward items for your hero.
Sony isn’t saying what more will be sold in the future so I guess we’ll have to just wait and see. DC Universe Online released for PS3 and PC. Will SOE move DC Universe Online into free-to-play territory in the future? Other MMOs have caught F2P fever.
