A scene of the Master Chief’s back side has delayed the release Halo 2 for the PC.

It has come to our attention that an unfortunate obscure content error which includes partial nudity was included in our initial production of Halo 2 for Windows Vista.

The game will now ship to distributors on May 31. Not quite sure where they could sneak in a backside scene, it does seem to be a glitch of some sort unless they have added a few cutscenes. The main point of this however is that they are just now releasing Halo 2 for the PC, whenever most people have already played it, beat it, played multiplayer, dropped it, and went back to it a year later only to trade it in two days later.
