Q: Passage: In December 2008, the CTO of Blitz Games announced that it would bring stereoscopic 3D gaming and movie viewing to Xbox 360 and PlayStation 3 with its own technology. This was first demonstrated publicly on PS3 using Sony's own technology in January 2009 at the Consumer Electronics Show. Journalists were shown Wipeout HD and Gran Turismo 5 Prologue in 3D as a demonstration of how the technology might work if it is implemented in the future. Firmware update 3.30 officially allowed PS3 titles to be played in 3D, requiring a compatible display for use. System software update 3.50 prepared it for 3D films. While the game itself must be programmed to take advantage of the 3D technology, titles may be patched to add in the functionality retroactively. Titles with such patches include Wipeout HD, Pain, and Super Stardust HD.
