Louise is a new unit introduced in Metal Slug Attack.
Louise excels in scouting for the Regular Army, and often goes on solo excursions. She is armed with a sniper rifle and also carries a radio to call in airstrikes on targets.
Her relationship with Berzek is unknown, but they have some value to her as she is troubled by their mysterious disappearance and cannot find closure until she finds them.
First debuting in "Tropical Battles", Louise recalls an incident three years ago where she was wounded in a mission. Berzek found and treated her injuries. During the night, they heard hostiles outside, and Berzek went out to confront them, despite Louise's protests. Louise would eventually be found by the Regular Army, though she is clearly troubled with Berzek's fate and began her search for them.
She monitors Rita's battle against Towa and reports it to Sophia. Sophia suggests that she should find some closure with the other girls since she has not found Berzek, but she refuses and resumes her search for them.
- Her bomber run special attack could be referenced to Natasha Volkova from Command & Conquer Red Alert 3.
