Lasers, Railgun, and guns that go "ZAP".

When Destiny was revealed over a year ago, I got hyped for some next level future weaponry. However so far all the types of guns we have seen so far have been pretty traditional; ARs, DMRs, LMGs, SMGs, Shotguns, Revolvers, BRs, and Sniper rifles. With the exception of Fusion rifles and pulse rifles, all of these gun types are stuff I can find in BF4 or CoD. What we need is something new, something creative, something decidedly Bungie. I remembered how when I first started playing Halo I got super psyched about the spartan laser, it was unique, it was a new experience, not just another automatic primary. I also had a similar experience with the gravity hammer, and the swordsplosion from BL2 Destiny needs some trademark guns, something which someone doesn't pick up and say "OMG, this looks like so and so...",or some noob sauntering up and saying; "wow look an AK47!!!". Does anybody here have any experiences with a unique gun, or an unique and original idea?
