If you look closely at the image of the initial three character classes, you might catch something different about the gun in the hands of the Hunter class. Specifically, the barrel. The barrel of the Hunter's gun is thicker then that of the others and seems to share a similar design with sound suppressors on present day firearms. It even as if the barrel itself isn't a barrel at all, instead some sort of attachment for the weapon. Is it possible we will have enhanced options for stealth and silent shooting that were mostly absent from Halo? I hope so. The stealthy style of play with precision weapons is my personal approach to most shooters so seeing the new dynamic in Destiny is something that appeals to me. For now, I can only speculate about the inclusion the inclusion of sound suppressors, but the difference on that barrel is more then a noticable one. Of course, I may just be overanalyzing it d it could simply turn into a muzzle break. Here's hoping for more stealth options in Destiny!
