Dynamite Blue is a 2.5D pixel-art turn-based tactical RPG set in a cyberpunk city, developed by Kosmo’s12, a new studio formed by former Exos Heroes developers. The global version launched on September 30, 2026 on iOS, Android, Steam and STOVE. This guide covers its gameplay, world, content and update roadmap.
What Is Dynamite Blue? Quick Facts
Dynamite Blue is a collectible RPG with turn-based combat that puts story and characters first. Players take the role of the owner of a small detective agency called Dynamite Blue, starting with petty jobs and gradually following cases that could shake the whole city. The game pitches itself as the story of a crew with no money and no connections that always gets the job done.

Kosmo’s12 and the Legacy of Exos Heroes
Kosmo’s12 is a Seoul-based studio that, according to its website, was founded in February 2026 by core members of the team behind Exos Heroes, published by Line Games, bringing more than 20 years of combined experience across console, mobile and PC. It is led by Youngzun Choi (CEO and director), with Minsuk Son as art director.
In an interview with PlayForum, the team said that after Exos Heroes ended service, their next project, 4GROUND9, never launched. Dynamite Blue was therefore made with the goal of showing players a finished product. It carries over part of 4GROUND9’s worldbuilding and applies lessons from Exos Heroes: a simpler early game and stronger character storytelling.
The World of Beerhaven and Jagear Technology
The game takes place in Beerhaven (some outlets write Vierhaven), a cyberpunk city where Jagear, technology that replaces body parts with machinery, has become widespread. The city is split into three layers: the Air Ground above for the privileged, the lawless Underground where no light reaches, and the Midground in between where ordinary people get by day to day. The Dynamite Blue agency sits in a small corner of the Midground.
Some Vietnamese outlets write the technology as "Zagier", while the official English materials use "Jagear". OtaHub follows the developer’s spelling.
Gameplay: Six Elements, Guardian Stone Break and BP

Combat in Dynamite Blue revolves around three main mechanics, all described in the official materials:
- Six-element matchups: each element is strong or weak against others, so building a team that fits the enemy decides much of the outcome.
- Guardian Stone Break: enemies are protected by element-based "guardian stones". Hitting the right weakness breaks the protection, puts the enemy in a broken state and opens a window for focused damage. According to 2Game’s introduction, chaining attacks that counter the element can also set up high-damage combos.
- BP (shared battle resource): the whole team builds and spends BP together, so every team composition plays differently rather than each character fighting alone.
According to the developers, the early game is intentionally simple, with only one active skill per character, and the systems grow more complex in the mid and late game. An AFK mode also means progression does not require constant screen time.
Content: Main Episodes, Pocket Stories and Jukebox Raids
The story is split into three layers. Main Episodes follow the detective agency and the cases across the city. Pocket Stories are personal tales for each of the 60-plus characters, covering their past, personality and relationships. Jukebox Raids are PvE boss content that also supplies extra narrative pieces for characters.
Art director Minsuk Son said the story fragments scattered across the game were calculated so that, pieced together, they reveal one person’s full story. PvP also features a "Today’s Gimmick" rule that boosts certain elements or rarities to stop everyone repeating the same team.

2.5D Pixel Art and a Cast of 60+ Characters
Dynamite Blue pairs pixel art with 2.5D environments, filled with neon streets, signage and TV-headed robots. According to art director Minsuk Son, the team moved away from an earlier 3D fantasy direction to pixel art because it conveys a character’s impression faster and more precisely given current development conditions. The studio’s website also stresses wallpaper-worthy character illustrations and a humorous cyberpunk tone that does not take itself too seriously.

Post-Launch Update Roadmap
The development team says its post-launch plan includes:
- Three new characters and one Main Episode every month.
- A Jukebox Raid update roughly every one to one and a half months.
- In preparation: new raids, a damage-race PvE mode, "Reel Tape" (a growth resource system), skill equipment and crafting content.
- Mid to long term: pet content and guild battles.
COO Heo Seong-uk said the team wants players to feel satisfied just returning when a new episode or raid arrives, which suggests an operating approach that does not force constant grinding.
Dynamite Blue PC Requirements and How to Play
Besides iOS and Android, Dynamite Blue has a PC version on Steam. When OtaHub checked, the game’s Steam page still showed "Coming soon" even though the developer announced a simultaneous September 30 launch, so PC players should confirm availability on the store or STOVE before downloading.

Tips for New Dynamite Blue Players
Based on the system design the developers have published, newcomers can consider:
- Learn the six-element matchup chart early, since breaking guardian stones quickly is the key to most fights.
- Build teams whose elements complement one another instead of stacking your strongest character, because BP is shared by the whole team.
- Read the Pocket Stories of the characters you use to understand them and the plot.
- Use AFK and x2 speed to save time on repeated stages.

OtaHub’s Take
Dynamite Blue is worth trying for fans of story-driven turn-based RPGs with striking pixel art and tactical combat. Its strengths are the Exos Heroes team’s experience, a simpler early game and an investment in character narrative. The caveats are that it has in-app purchases and a character-collecting design, so players should understand how characters are obtained before spending money, and it has no Vietnamese language yet.
