Heavy Railgun requires and consumes 1 round of ammo (re-balance patch changed ammo consumption from 3 to 1).
Chung will fire one cannonball which crosses the screen (approximately 800-1000 range at most) and pierces all enemies in its path. Any enemies that survive the initial hit will be hit by a secondary hit from the trajectory of the initial shot, dealing less damage and launching targets into the air. The secondary explosions can hit any target within range, so this skill is the most effective when groups are huddled close together.

Using Heavy Railgun at point blank range will result in either a single hit or no hits at all if the target is same size or smaller than Chung.

Recently nerfed in the 07/28/11 character re-balance patch to do ~250% less damage than before, and the secondary hit has a decreased aoe radius (smaller than Fury Guardian's Steel Edge without the note).
