Halo: Combat Evolved (Xbox) August-September Pre Release Trailer [High Quality]
Judging from the games trailer, some of the clips used are from the August Beta Build and sometimes it uses a later version of that build. I don’t know exactly when this trailer was first shown, but the way the game looks seems to take place between August and September, not to mention the ESRB Rated Halo a “T” Rated game before changing it to Rated “M”.
