Ever since Halo: Combat Evolved I have loved testing the boundaries of the space given to me to play in and exceeding those boundaries. Back then it was a lot simpler to leave the play area alive with the player although in those days there wasn't anything like there is now in terms of a sky box. Basically outside the play area were flat textures and little to no real geometry. Halo 2 arrives and with it a glitch revolution. Super bounces, butterflying, cloning, dummy-ing, XBR/YBR and like before I enjoyed leaving the play area and exploring. Utilizing super bounces and sword canceling techniques I would explore the outer reaches of Burial Mounds, Waterworks, HeadLong, etc. Unfortunately, as I did not have a capture card and these two early games had no way of recording imagery without one I don't have any images of these games to share.
With Halo 3 came the invention of Theater mode and Bungie grew more clever with their boundary system. Now most maps would auto-kill you if you passed the boundary instead of just blocking you with an invisible wall. Bungie also somehow knew these measures wouldn't be enough so they put invisible walls up all over the place just beyond the auto-death barriers in case people tried to out-smart the system. However, I found with enough banging up against barriers in theater mode I could get past them and explore the beautiful scenery that Bungie had for some reason modeled past where the player could actually see in the levels (The Pan Cam glitch I discovered later helped a lot too in Halo 3).
