Atomic Games' Breach was big news coming out of PAX East this year due to the theft of some of its netcode by a criminal mastermind. Since then, there has been little news on the game, including when it missed the expected June release window.
Atomic Games announced earlier today that Breach has been pushed back to January 2011. The game is finished and ready to ship, but because of the XBLA marketplace schedule, January is the earliest available date.
To make up for the delay, Atomic Games is going to continue working on Breach and will be adding a "Hardcore" mode with added realism.
