Until PlayStation Store returns, Warner Bros. has suspended the "Kombat Pass," the one-use code (included free in retail copies) that enables online play for Mortal Kombat. That means anyone with a copy of the game, used or new, can play online for free. However, when PlayStation Store comes online, "users will be able to enter the Kombat Pass code included with Mortal Kombat or purchase a Kombat Pass for $9.99." As the service is expected to return on Tuesday, this means anyone who buys a used copy of the game now gets a free weekend of online play, more or less. Yippee.
