I want one

A belt fed externally powered fully automatic nerf autocannon:

N-STRIKE VULCAN EBF-25

(Ages 6 years & up/Approximate Retail Price: $39.99/Available: Fall 2008)

The top-of-the-line blaster for mission supremacy, the NERF N-STRIKE VULCAN EBF-25 blaster is a 25-dart belt-fed fully automatic blaster that will intimidate any opponent. This impressive blaster comes complete with a fold-up tripod to steady your aim, 25 sonic micro darts that whistle through the air when launched and a 25-dart belt. The NERF N-STRIKE VULCAN EBF-25 blaster features the Tactical Rail System allowing players to customize their blaster for each mission - for example, players can use the green 'night vision' Tactical Light accessory (sold separately) for nighttime missions. Six "D" batteries are required but not included.

SIX D cells?!? That's a lot of power. This would've come in handy for those dorm nerf wars. All we had back then were six shooters and a carbine or two. Now they've got sniper rifles, RPGs, autocannons, and apparently rocket launchers. Hook up one of those rocket launchers with the autocannon and you've got quite the nice dorm room defense set up. Regardless, I'm still buying one. If you're into this sort of thing, Nerf's N-Strike line has some pretty impressive hardware.
