Double Stallion has rolled out a Steam demo for Surfpunk, a new action RPG built around four-player co-op, pirate combat and a sprint to escape before a tsunami wipes the map clean. The studio also said the game will officially support Korean subtitles when it reaches Early Access.

Surfpunk casts players as Raiders moving across procedurally generated tropical islands on boards, with the action built around a “surf-and-slash” loop of hacking through swarming enemies, grabbing loot and getting out before the wave hits. The demo is being shown at a booth at BitSummit in Kyoto, Japan, giving the team a live test of a game that is already playable on Steam.

For Double Stallion, the project arrives after it previously released Time/Cross: A League of Legends Story, which centered on the champion Ekko and helped establish the studio as a developer able to handle a recognizable universe. Surfpunk is a different pitch, but it follows the same basic promise: a tightly designed action game with enough style to make the grind feel like part of the show.

Eric Angelillo described Surfpunk as a cooperative action RPG, and said its combat takes cues from hack-and-slash games such as Raven's Watch, Hades and League of Legends, while the broader management and mission structure is meant to feel closer to Monster Hunter or Helldivers. He said it is not a roguelike, because players take on missions with specific objectives, and that each mission includes a map with randomly accessible islands where hidden objectives can be found along the way.

That design matters because Surfpunk is not just asking players to survive waves of enemies; it is asking them to balance speed, loot and role coordination across four distinct weapon types while the sea closes in. The Korean subtitle support also signals that Double Stallion is treating the Early Access launch as a wider commercial step, not just a demo-stage experiment.

The big test now is whether the mix of co-op progression, mission-based objectives and fast escape pacing can hold attention once the novelty of surfing into battle wears off. For now, the studio has put the game in players' hands, and it is betting that the easiest way to sell a pirate fantasy is to make the tide the enemy.
