In-Game Description
"A super-heavy tank. A barrage weapon with long range that can perform several strikes at once"
Shoekarn

Karn is a Super Rare unit appearing in Metal Slug Attack. Much like its twin brother, Shoe, Karn shares similar attack damage, health, production, required items, etc. The most obvious differences between the two are their special attacks and AP costs (with Karn being slightly more expensive and powerful). Karn's unit parts are available via Battle Shop or Elite 8-6.

Compared to Shoe, Karn's special attack launches more projectiles; however, it lacks the anti-air capabilities that Shoe has with its special. It can be considered an inferior version of the Iron Nokana, considering that both units rely on mass projectiles for damage.

Attacks

Long Range

Attribute grenade Cannon/Missile (Spread) - Fires three shots from both its main cannon and mini-turrets, launching missiles at the same time.

Special Attack

Attribute grenade Rapid-Fire Cannon (Spread) - Fires multiple shots against its enemies. With MSA Skill small + 2, Karn fires more shots from its cannon. With MSA Skill small + 4, a rebel soldier will appear from the hatch and fire projectiles as well.
