The RAGE Website notes a new Arsenal Gameplay Montage trailer on GameTrailers.com showing off the weapons in id Software's upcoming first-person shooter. Included are a couple of machine guns, an unattended turret, a boomerang dealie, a shotgun (of course), and more. There is also a warning to watch your back in the sewers, followed by footage of nothing but frontal assaults from the sewer denizens. Thanks Bill.
