After being leaked this morning, the Halo Reach beta trailer is now official. Bungie promised something new, and they were not lying… jetpacks. Lots, and lots of jetpacks.
That brings up the question why jetpacks were not part of prior Halo games, but hopefully that little plot hole is cleared up somewhere in the story. Other new additions (besides unnamed weapons) are gameplay modes like Invasion, new melee combat, specific weapons loadouts, and awesome looking assassinations. Obviously, this is a tease for the May 3rd launch, but it looks spectacular, and even faster paced than the usual Halo romp.
