Scotia Amundsen is a unit original to Metal Slug Attack, first appearing in the Extra Ops titled Mummy's (as a pre-acquisition unit, obtained by purchasing 10,000 medals). She fires ricocheting shots which cover a large area in front of her, piercing any enemies they come in contact with and easily striking aerial targets. Her special attack, when sufficiently upgraded, can additionally knockback enemies. Larger units tend to get held back as the shots contact them multiple times - smaller units, on the other hand, are often able to make it through her barrage.
