When it unlocks
The store page says November 13, 2026. When we checked at about 12:30 Beijing time on November 13, the page still said the game would unlock in approximately 13 hours — that points to roughly 01:30 Beijing time on November 14. That is an observation of Steam’s countdown, not an announced time: Valve’s countdown can move, and regional stores can flip at different moments.
If you want to be there at unlock, wishlist the game and let Steam notify you. There is no pre-purchase and no pre-load listed.
Price
No price yet. On November 13 the store had no price block, no pre-purchase button and no launch-discount banner. The demo is free. We are not guessing a number; when the store shows one, this page will carry it with the check date.

There is no Mac or Linux build listed, and no console version. If you see a “PS5” or “Switch” result for Water TD, it is almost certainly about a different game with the same generic name.
Languages
The store lists 29 interface languages, including English, French, Italian, German, Spanish (Spain and Latin America), Japanese, Korean, Simplified Chinese, Traditional Chinese, Russian, Polish, Turkish, Vietnamese and Indonesian. The store page marks interface only — no full audio or subtitles are listed. That matters for a game whose tutorial and tooltips carry the rules.
What is in the launch build
These are the developer-confirmed features from the store page and the official trailer:
- 7 turrets, each with two builds that change how it fights.
- 4 abilities: a fireball, an ice/frost wall, a lightning strike and a power that sends the flood back.
- 170+ skill-tree upgrades, bought with three point types: Basic, Clear and Perfect.
- Levels are separate maps, each with its own flood to hold back; the trailer shows Level 10.
- The core rule: water flows downhill, piles up, finds gaps and erodes the riverbanks; a turret on a collapsing bank goes down with it.
Two things the demo’s players report but the store page does not spell out: challenge mode and horde mode for levels. We cover both on the levels page.
Should you wait for launch or play the demo?
Play the demo now if you want to learn the economy before launch. It is free, it has the same turret-and-skill-tree structure, and the demo discussions already show what the first levels punish: building on the outer bank, spending Clear points on stat nodes before unlocking a second turret, and ignoring the fan turret. The demo guide has a checklist of what to test.
What the demo will not tell you: the launch price, whether demo saves carry over (not announced), and how the later levels and modes are tuned. Treat the demo as a lab, not as a progress save.
What we still do not know
- The exact unlock hour (Steam countdown only at our check).
- The price and whether there is a launch discount.
- Whether demo progress carries into the full game.
- Build names, level names and the full upgrade list.
- Steam Deck verification.
We update this page after launch rather than filling the gaps with guesses.
