Outerplane, the strategic isekai RPG developed by VAGAMES (the team behind Closers) and published globally by Major9, has officially kicked off its 3rd anniversary celebration. Pre-registration for the anniversary opened on May 1, and the major version update is set to go live on May 19.

This update brings fan-favorite character Skadi back in a limited-edition phantom thief form, alongside a brand-new event story, high-difficulty PvE content, an increased character growth cap, and a long-awaited Partner Interaction system. The overall volume of rewards is substantial.
Pre-Registration Perks: 3 Limited Outfits and 3,333 Ether Up for Grabs

A proper anniversary celebration needs generous handouts, and Outerplane is sticking to the Korean live-service tradition of pre-registration rewards.
From May 1 through May 14, players can sign up on the official 3rd anniversary pre-registration page to claim the following once the update drops:
- 3 limited outfits (Kanon, Tamara, and Lay)
- 3,333 Ether
- 33 limited recruitment tickets
These resources should give both new and returning players a solid head start heading into the new content.
Main Attraction: Skadi’s “Midnight Rush” Phantom Thief Form

Limited anniversary units are always the centerpiece, and this year the spotlight is on Skadi.
Launching with the May 19 update, Skadi returns as the 3rd anniversary limited unit “Midnight Rush Skadi,” sporting a bold, flashy phantom thief look. She is a Fire-element Attacker. This form blends theatrical flair with a daring aesthetic, complete with exclusive animations and striking skill effects. As a limited unit, her combat performance is not likely to disappoint—overseas previews have already noted her “insane damage output.”
New Story: A Phantom Thief Operation Built on Debt and Conspiracy
A new character means a new story to go with her.
The 3rd anniversary update introduces the event story “Heist Class, Highest Class.” The narrative follows Skadi as she sets her past aside and teams up with Lay, who is determined to prove her own growth. Together, they plunge into a tense phantom thief operation entangled with debt and hidden schemes. Players can expect deeper insight into the bond and emotional evolution between the characters as the story unfolds.
Character-focused event stories are a familiar format for gacha game anniversaries, but the real draw here will be how well the classic “phantom thief” theme is executed.
Key New Content at a Glance

1. Partner Interaction System: Finally, Some Bonding Time
For a game that sells itself on character collection and narrative immersion, Outerplane was noticeably light on one-on-one interaction. That changes on May 19 with the introduction of the Partner Interaction system. Players will now be able to engage with their characters through a variety of interactive features, deepening bonds and adding a new layer to the role-playing experience. For anyone who has been craving more “sweet moments” outside the main story, this is arguably the biggest surprise of the update.
2. Increased Character Growth Cap
Alongside the anniversary update, the character growth cap is being raised across the board. This means squad power gets another bump, and players can tackle even higher-difficulty content. For veteran players who have been in a holding pattern, this injects a fresh sense of progression into the existing systems.
3. High-Difficulty PvE: Dimensional Singularity
Players at the top need a battlefield that matches their strength. On May 6, Outerplane opened the new high-difficulty PvE mode “Dimensional Singularity” ahead of the main update. This content is designed specifically for seasoned players, offering a steep strategic challenge that demands careful team composition and tactical planning.
Cosmetic Feast: 3 New Outfits
Beyond Skadi’s limited form, three new character outfits themed around “Midnight Rush” are also arriving, for Lay, Dian, and Eris respectively. These skins continue Outerplane’s polished anime art style. For fashion-focused players, picking up a few anniversary outfits and exploring the continent in style sounds like a perfectly valid way to celebrate.
Offline Event: Illustar Fest 11 in Goyang
The anniversary is not confined to in-game content. Outerplane will also have a presence at “Illustar Fest 11,” taking place May 23–24 at KINTEX in Goyang, South Korea. On-site activities include cosplayer events, exclusive anniversary merchandise sales, a photo book release, and hands-on player events.
Final Thoughts

Outerplane comes from the core team behind the well-known MMO Closers. As a strategic isekai RPG, it has carved out a stable niche in the overseas market with its polished 2D art, fluid turn-based combat animations, and a cast of distinctive, charming characters.
This 3rd anniversary update does not just expand the roster with a powerful limited unit—it also reinforces two key pillars of the game through the Partner Interaction system and the raised growth cap: strategic depth and character bonding. If you are drawn to the combination of Korean-style strategy and high-quality art, now is a great time to jump in. Anniversary reward windows, after all, tend to be the most generous point in any mobile game’s calendar.
