"NBA 2K15" Patch 4, already made available for the PS4 and PC, still has no definitive release date for the Xbox One, but gameplay changes, new locker codes, and a March 24 roster update has just been released. 

The most notable change is the inclusion of players that were previously left out due to injuries. Players that have made it back in the real world after the "NBA All-Stars" will be returning to the game roster, creating new and updated line-ups. 

Existing players will also see a few attribute changes. The roster update is quite extensive, but some of the most stand-out alterations include Kyrie Irving's total attributes raised to 89, Tony Snell hitting 75, and Dante Exum gaining three additional points for a total of 74. 

Some players got their attributes knocked down as well. The Charlotte Hornets' Brian Roberts went down by three points while Dahntay Jones from the LA Clippers went down by one, among others. 

Meanwhile, a new locker code has been released via Twitter. The locker code "MRQ6P-JJ6XG-AQRV7-TFMXU-3U62C" will bring NBA legend Larry Bird to the game's "My Team" roster. 

In the Operation Sports forum, Gameplay Director Mike Wang posted that Patch 4 also came with slight changes to the shooting system. 

"I tuned the baseline shooting values that are shared by both human and CPU-controlled players," Wang posted. "I also fixed the 'glitched' shots being unable to get perfect release, so that will factor in as well." 

The shooting system is not the only area of the game being refined with the new patch. A recurring shoe glitch is being addressed, as well as an error with the "NBA 2K15 MyPark" mode. 

Previous updates for "NBA 2K15" included over 150 Legendary players, St. Patrick's Day uniforms, and additional accessories for players alongside the regular roster update.
