I was playing halo2 campaign on my 360 and I noticed that some images get burned into the screen. I snapped pictures of the arbiter's silhouette, burned into the left side of the screen. One of those bigger forerunner robots also got burned into the screen.

if it ever happens, just have someone from the other team shoot you once and jump off the edge... And make sure that when you are turning off ur 360 to sign all the way out, to the press start screen, and then go to the Dashboard before shutting it down. Pressing the power button or using the controller ingame has adverse effects... (especially during an XBL game, where it looks like you were standbyed out to your teammates.)
