343 just dropped a brand new trailer that focuses on all of the weapons at the UNSC's disposal in Halo 4. There are some familiar ones on display, but a couple of brand new guns get shown off too.
First up is the Light Machine Gun called SAW. Wait, wait, wait! An LMG in Halo?! Whoa. Even more impressive is the 72 rounds it can hold with each clip. Then there's the Railgun, a powerful accelerator that fires explosive rounds. Kind of makes me think of it like a mini version of the MAC.
Check out the recent Halo Bulletin for a full breakdown of the weapons, with commentary by various 343 team members describing how each gun feels.
