As part of the collaboration, three iconic characters from Metal Slug 3 (Eri Kasamoto, Marco Rossi, and Fio Germi) arrive as new Legendary fighters. Players will have a chance to acquire Eri Kasamoto and Marco Rossi through special Pick-Up Events from February 11 to March 10, while Fio Germi will join the roster on February 15. Special events and dungeons to celebrate the collaboration are also available through March 10:

Metal Slug 3 Collab Check-In: Log in during the event period to earn rewards, such as the Legendary fighter Marco Rossi on Day 1 and the Legendary pet Pocket SV-001 which is inspired by the signature METAL SLUG tank vehicle, on Day 7.
Event Dungeon: Final Mission & Air Defense: In this score-based dungeon, players will team up with familiar bosses from The King Of Fighters AFK to take down Roots Mars of Disaster, a KOF-style reimagining of Metal Slug 3's final boss Roots Mars. Players can earn ranking rewards based on their scores, and daily play rewards grant event currency used in Air Defense.
- In Air Defense, players can use the currency to access a special draw event featuring Metal Slug 3 characters Tarma Roving, Donald Morden, and Aikawa Madoka as Legendary supporters, along with fan-favorite character Ichimonji Hyakutaro as a Unique supporter.
Event Dungeon: Assault Mission: Take on this limited-time tower-mode event dungeon and clear each stage to earn Fighter Tokens, which can be used to summon collaboration fighters.

Additionally, the Metal Slug 3 Collaboration Event will run from February 17 to March 10, offering opportunities to obtain the Legendary pets Pocket Mars People and Pocket SV-001. Players can also earn bonus rewards by discovering hidden Ichimonji Hyakutaro throughout the game. Alongside the collaboration update, The King Of Fighters AFK is rolling out a new Challenge Dungeon and a dedicated returning player event.

The new Challenge Dungeon, Count Down Operation, offers a tactical experience where players can strategically build up to five decks with a total roster of up to 25 fighters to defeat bosses. Returning players who resume play on the server they previously played on will receive 14 days of returning benefits, and a Return Celebration Pass will offer chances to obtain Orochi, Orochi Iori, and Orochi Leona. Players who return but transfer to a different server will also receive special benefits. More details are available on the official forum.
