"The heavy version of the bolt launcher deals more damage per hit than its lighter counterpart." In-game description.
This weapon offers the Doombringer a powerful explosive weapon with longer range than the Titan Launcher. It is typically used indoors because of it's slow projectile speed. When fired, an energized projectile is launched in a short arc that explodes on impact. The Heavy Bolt Launcher is similar to the Brute's Heavy Spinfusor in the fact that it fires an explosive projectile, has the same damage on a direct hit, but the Heavy Bolt launcher has an arc, so it is neccesary to fire above the intended target. This weapon has a reasonably good AoE and can be very deadly at close range. The primary drawback of the Heavy Bolt Launcher is it's atrocious reloading time. The only weapons which reload slower are the Mortars and Saber Launcher.
