The strategy game expands beyond mobile with online multiplayer, over 40 playable characters, and a fresh twist on classic Reversi.

El Shaddai: Zero Nine Reversi is now available on PC through Steam, bringing its distinctive take on the classic Reversi board game to a wider audience. Developed by crim, the game introduces a battle-focused twist to traditional tile-flipping gameplay, combining strategy, character abilities, and resource management.

The PC version launches at $3.59 with a limited-time 10% discount. The price will increase to $3.99 after November 15.

Previously released for iOS and Android on April 27, the game also received a mobile update alongside its PC launch. The update introduces online multiplayer support and a new archive feature across platforms.

Unlike traditional Reversi, where players focus on capturing territory by flipping their opponent's pieces, Zero Nine Reversi gives every stone its own health points (HP).

Whenever a stone gets flipped, it loses one HP. Once its health reaches zero, the stone disappears from the board entirely. This additional mechanic turns every match into a strategic battle of positioning, timing, and resource management.

Players can choose between two main modes:

• Classic Mode: A single-player experience featuring challenging AI opponents, multiple board sizes, special rules, and an expanding collection of character stories.
• Online Mode: A competitive multiplayer experience where players select characters with individual attributes and special abilities to battle opponents.

Classic Mode offers more than 40 character stories featuring angels and fallen angels, complete with original artwork and animated sequences. Players can earn Rank Points to unlock additional content while exploring the game's world and familiar characters, including Enoch, Lucifel, and Michael.

There are also several board configurations, ranging from a compact 6×6 Mini board to the traditional 8×8 layout and a larger cross-shaped 12×12 Annexation board.

Additional features include five AI difficulty levels, daily challenges that refresh every 12 hours, special gameplay rules, and worldwide online rankings shared across platforms. Keyboard and mouse support also makes the PC version accessible to players who prefer traditional desktop controls.

Online Mode adds another layer of strategy through its BUMP & BURST mechanic. Instead of simply losing one HP when flipped, stones lose health based on the attacking character's power. Once their HP reaches zero, they burst and leave an empty space on the board.

Players can choose from more than 40 characters, each with different health values, attack power, and unique abilities. These abilities introduce different approaches to competitive matches, making character selection an important part of the strategy.

Multiplayer options include:

• Random Match: Compete against players from around the world while building a record and ranking.
• Private Matches: Invite friends using room codes.
• Team Battle: Join a 2-versus-2 match and coordinate strategies with a teammate.
• Offline Play: Challenge the CPU, play locally with another person, or enjoy team battles on the same screen.

An archive system also lets players spend Gold earned from battles to unlock additional characters, titles, visual effects, and backgrounds. Daily tasks provide further opportunities to earn rewards.

With its combination of familiar board-game mechanics, character-driven battles, and competitive multiplayer, El Shaddai: Zero Nine Reversi offers a different way to experience Reversi on PC and mobile.
