2K confirmed that the 7 Perfect Game Challenge will be returning, but will now have many different rules.[3]
2K confirmed for the second straight year that there will be a 2K combo pack that includes MLB 2K13 and NBA 2K13. The NBA cover will only feature Kevin Durant of the Oklahoma City Thunder on it instead of the trio of Durant, Blake Griffin of the Los Angeles Clippers, and Derrick Rose of the Chicago Bulls. Its retail price was $79.99 and was released on March 5.[4]
There are no gameplay or game mode additions compared to MLB 2K12, and it is missing online leagues.[5] This is most likely because 2K only had four months to make the game due to the contract expiration.
