Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Damage Chess is fully playable today, but two of our planned pillars — ranked online matchmaking and server-side clock arbitration — directly affect competitive fairness, and we believe they must be designed and tuned together with a real player community rather than in isolation.
”

Approximately how long will this game be in Early Access?

“Approximately 6 to 12 months.”

How is the full version planned to differ from the Early Access version?

“Planned additions for the full release: ranked matchmaking, server-side clock arbitration, balance presets, Steam achievements, and additional language support.”

What is the current state of the Early Access version?

“Fully playable and stable: 4-tier CPU opponents, online matches with friends (invite / room code, with reconnection support), all chess special moves implemented (castling, en passant, double-step, Q/R/B/N promotion), fully customizable rules and piece stats, and complete Japanese / English UI.
”

Will the game be priced differently during and after Early Access?

“No. The price will remain the same when the game leaves Early Access.”

How are you planning on involving the Community in your development process?

“Feedback from Steam forums and reviews will directly shape balance tuning and the priority of upcoming features.”

About This Game

A chess where you don't capture — you grind them down.

Damage Chess rebuilds chess around HP, Attack and Defense. Pieces no longer fall in one hit. You chip away their HP, and only defeat them when it reaches zero. Damage is randomized, and an attacked piece may strike back. Every square becomes a gamble.

Three actions a turn — dense, deliberate play.

Instead of one move, you take three actions per turn. Advance, corner them, and strike. There is no checkmate — the first player to burn the enemy King's HP to zero wins.

Chess's special moves, weaponized.

Castle to shelter your King, stab with en passant, and choose Q/R/B/N on promotion (current HP carries over). The classic rules mesh with HP combat into something new.

Tune the luck yourself.

Damage variance, counter success rate, actions per turn, special-rule toggles — the rules are yours. You can even edit each piece's HP, Attack and Defense individually.

A CPU with real bite — and friends around the world.

Four CPU tiers: Weak / Normal / Strong / Expert. Play friends online (invite / room code, reconnection support).
