Hey,
Halo 4's coming out soon and you want to see some of the Covenant weapons, right? Of course you do. 343's put up a new video showcasing a bunch of the Covenant weapons in montage form. All the weapons are shown in a deathmatch scenario in two of their War Games maps. I haven't played a Halo game in a long time, but I recognize many of the returning weapons and they do look like they've had a nice upgrade since I was playing the series.
