Found CRITICAL BUG in Quake IV...
After some experimenting with Quake IV for the XBox 360, I found a CRITICAL BUG! I forwarded this message to the Software Testing/Quality Group from Activision for a fix (if they don't already know about it.)
I tried this several times and it locked the XBox 360 each time during the "Loading" screen for the next section on Level 1.
1) When you press the B button to "Exit"; if your holding the machine gun when you exit, the "Loading" screen will freeze (and the XBox 360 will lock), after 3 or 4 "green swipes" on the loading screen.
2) I changed the machine gun to the "blaster" (original gun) and exited, by pressing B. The next level loaded every time...no more freezing on the loading screen or locking the XBox 360.
- With this blaster method, I did receive an "XBox Live Error" Screen and then the screen for the hard-drive save. I saved the game on the hard drive and continued playing the next level.
I'm not sure if the bug is related to other settings on my XBox 360; (I offered to discuss my issue in detail with the Activision Team; ie settings on the XBox 360; hardware; serial numbers; dashboard revisions, etc.).
The Activision Tech Support offered no assistance, other than clean the disk (it's brand new), reset the XBox 360 and then contact MS.
Hopefully, this helps other people in the forum. I have read that other people have the exact same issue.
