Vatn is a unit original to Metal Slug Attack, first appearing in the Extra Ops titled Halloween Train (as a pre-acquisition unit, obtained by purchasing 10,000 medals). He serves as an expy of Van Helsing.
As a standard melee attack, Vatn equips a drill on his gun, dealing rapid melee damage. Unfortunately, this requires the enemy to be very close to him, or he will use his ranged attack instead. He fires his Gatling gun at enemies away from him, dealing less damage but shoots many bullets. With 3, he will shoot more per attack. Vatn's greatest selling point are his deployable mortars. These mortars are invulnerable to enemy attacks, cover a wide range, and deals decent damage (with high resistance lowering).
Setting them up with "Reload" can make multiple mortars in rapid succession, resulting in a flurry of mortar shells. Two or more mortars hitting an unshielded enemy can cause havoc on them, as they will be continually knocked back while taking damage in the process. They are especially notorious for destroying enemy bases early game if the opponent does not place a unit to tank the incoming mortars.
Vatn has the ability to evade attacks when 4 is unlocked. When triggered, he uses his cloak to vanish and reappear a short distance away. It is useful for helping him to survive longer so he can deploy more mortars.
If Vatn is defeated, he will grab a bomb from his coat and ignite it as a parting gift. Upon exploding, a medium-sized projectile will fly in a smaller arc, dealing massive damage to enemies hit by it.
