The Beatles once opined that happiness is a warm gun. Skyforge's Gunner class has a warm gun that also transforms into different modes and allows the class to call down orbital strikes, so one can only conclude that it is a very happy class indeed. Its opponents are somewhat less so. You can see the class in action in the video just past the break, or you can read through the reveal page to get a better idea of how this multi-mode class will play.
The cannon has three main modes as well as a variety of sub-firing options, allowing gunners to mow down targets at long range with missile barrages or take out hardened targets with bursts of plasma. Since it's meant to stay at range, the class also sports a variety of defensive tricks like teleporting back and forth. It's exactly the sort of class for you if you like having a big gun, even more so if you want that big gun to shoot all sorts of different stuff.
