Halloween Forest is the two hundred and eleventh Extra Ops and the second Recapture introduced in Metal Slug Attack.

Story

Heidern tasks Leona to investigate an island that "appeared" from nowhere alone, as the Advance Unit sent there have been killed. Ralf and Clark express worry about Leona being sent alone and offer to assist her, but Heidern states that the mission requires only one of his men. Leona reassures the two that she'll be fine.

On the island, Leona is paired with Victoria. Leona smells rot and realizes that zombies are around, having recognized the smell from her Halloween mission. Victoria sends Wade to scout the area, discovering the presence of zombies and survivors on the island. The two work quickly to rescue the survivors and eliminate the threat on the island.

In the first location, the pair run into Caroline, who is partying with a group of zombies. Victoria wonders if she needs help while Leona is completely unamused. Caroline states that the zombies are friendly for the time being, but won't be if they break out of their Halloween mood. She offers them some pumpkins as a reward. Leona tells Caroline that her gut is telling her to beat her up, much to the mechanic's surprise, while Victoria has Wade prepare for battle.

In the second location, Alma is seen rejoicing with the ancient, yet intact ecosystem as she believes she can transform into one of the beings that used to live during prehistoric times. Victoria comments that the survivors are energetic and wonders if they need help. Alma has a group of zombies following her, stating that she doesn't feel like winning and needs their help, offering them some pumpkins as a reward. She stops Victoria from getting too close and messing with the samples she wishes to acquire, while Leona states that she won't be as lenient if she gets in her way.

In the third location, Percier is being chased by zombies as she runs into Victoria and Leona. Leona asks what she's doing on the island and Percier states that her spaceship crashed on the island. Victoria confirms her claims and notices zombies pouring out of the ship. Percier explains that she was sent by the Professor to mess with the Rebel Army, but the zombies somehow defrosted and broke out of stasis before they could be brainwashed. She offers them some pumpkins as a reward. Both have pity on her but Leona states that she will be punished first.

The two eventually find a Queen Big Snail, who flees after a short battle. Victoria tries to send Wade to go after it, but Leona stops her as they now know how to scare it off, and that they should prioritize the discovery of survivors first. Victoria agrees and has Wade start scouting for other survivors.

Trivia

• Upon release, there was a bug in which raids would yield more points than usual due to a coding error. The bug was fixed and no punishment was given to players who had abused it; players also received compensation for it.
