Dude, it's a railgun with engines strapped to it! How can I dislike it? I like how smooth it looks while still retaining that Human element to it! However, the UNSC logo looks like it's missing the 'SC' part of it. Me like it though!
If you were to take this ship and take away the engine housing and hanger bays and turn the lower cargo bay into a pistol grip and add a trigger in front and turn the bottom in the pump slider and length it just a little it would look a like the Halo 4 pump shotgun.
Kinda. This is a variant of my Nevada class which was in turn my attempt to make a Halo frigate out of one of the in-game weapons. Don't ask me why, but when I first saw the Railgun desig in Halo 4 I immediately just thought; "FRIGATE!!"
