Kingdom Rush 6: Genesis TD, Ironhide Game Studio’s prequel to its tower-defence series, launches on 24 September 2026, just three days away as of 21 September, on Android, iOS and Steam. It is a premium purchase, listed at US$6.99 on the App Store, with a free demo already on Steam. This is what Ironhide, the store listings and press confirm ahead of release, and what still needs checking on Google Play.
Title, date and platforms
Ironhide’s announcement, published 5 June 2026, sets the release for 24 September 2026 on mobile and Steam, and links directly to the Google Play listing (package com.ironhidegames.android.kingdomrush6.genesis), the App Store listing and a Steam demo. The App Store shows an expected date of 24 September. Steam lists the same date, with Windows and Mac versions and partial controller support. Ironhide is both developer and publisher.
What is in the game
The App Store listing gives the content counts, which are the most concrete thing known about the game today:
- 15 towers, each with its own upgrade tree
- 12 heroes
- 9 spells
- 18 campaign stages spread across three landscapes
- more than 40 enemy types
- 6 bosses
- more than 50 achievements
- offline play
The story angle, paraphrasing the Steam description, is a prequel: a young Vez’nan and the early days of Linirea, before the events of the original Kingdom Rush. The listing rates it 9+.
Price
The App Store lists Kingdom Rush 6 at US$6.99 as a one-off purchase. That is the only price verified for this article. The Google Play page did not load in a readable form, so the Android price is unconfirmed; do not assume it matches until the listing shows it. Australian pricing in either store was not captured, so no A$ figure is given here, and no Steam price was captured either.
Premium is the point. There is no free-to-play tier listed and no in-app purchase range on the App Store page, which for a mobile tower-defence game in 2026 is notable in itself. For Australians the practical check is the AU App Store or Play price on 24 September, or the Steam page if a Windows or Mac screen suits you better; Steam lists partial controller support for that version.
Size and requirements
On iOS the download is 459.6 MB and it requires iOS 13 or later, with visionOS also listed. That is a light install and a generous compatibility floor. Android requirements are unverified for the same reason as the price.
Try it first on Steam
If you have a PC or Mac, you do not have to wait for the 24th to see how it plays. Ironhide’s announcement links to a free Steam demo, which has its own listing (Steam app 4669880) separate from the main game page. Gamingonphone reports that the demo covers four of the 18 stages, two heroes, five towers, three spells and the Iron mode challenge variant. That scope comes from press rather than from Ironhide’s page, but the demo itself is listed by Ironhide. Because the mobile version is a one-off purchase with no trial mentioned on the App Store, the Steam demo is currently the only way to sample it before paying.
System requirements for PC players
Windows players need at least a quad-core 64-bit processor and Windows 10, with 8 GB RAM, Intel UHD 600 graphics, and 3 GB free storage. Mac users require macOS 10.13 or later with an Apple M1 or Intel Core M processor, 8 GB RAM, and OpenGL 3.0 compliant graphics with 1 GB video RAM. The same 3 GB storage footprint applies to both platforms. Steam’s partial controller support means that players on Windows and Mac with a compatible gamepad can play without the keyboard and mouse, though touch or keyboard remains the primary input method on mobile.
Gameplay mechanics and character synergy
The 27 upgradeable characters—combining the 15 towers, 12 heroes, and 9 spells—form the strategic core of Kingdom Rush 6. Each tower has its own upgrade tree, and heroes and spells can be tuned independently. Critically, players can retune their tower, hero and spell loadout between campaign stages, allowing strategy adjustments as enemies scale up. This flexibility distinguishes the game from tower-defence titles that lock decisions at map start. The 40+ enemies split across 5 distinct races, each with different resistances and behaviours, create asymmetric challenge patterns that reward synergy-aware lineup choices. Offline play means the entire campaign, including all 18 stages across three landscapes, works without an internet connection.
Story and setting: the origins of Linirea
The game’s narrative positions Kingdom Rush 6 as a prequel to the series. Players witness the early days of Linirea and a young Vez’nan—the antagonist of later games—before he became the figure known from the original Kingdom Rush. This framing recontextualises the tower-defence formula: each stage represents a pivotal moment in the kingdom’s foundation, with the 6 colossal bosses serving as major story beats. The campaign unfolds across three distinct landscapes, each tied to different regions of Linirea’s early history.
Languages and accessibility
The game is available in English plus 9 additional languages: French, German, Japanese, Korean, Portuguese-Brazil, Russian, Simplified Chinese, Spanish-Latin America, and Traditional Chinese. The iOS age rating of 9+ reflects infrequent cartoon and fantasy violence typical of the series. No hands-on accessibility testing has been reported, but the game’s strategy-focused design (as opposed to action-heavy gameplay) may suit players with different dexterity profiles.
Steam achievements and online features
On PC, the Steam version includes Steam Achievements (50+ in-game achievements reflected in the Steam backend), Steam Cloud support for save synchronisation, and Family Sharing compatibility. These features are specific to the Steam release and do not carry over to iOS or Android versions, which use their respective platform ecosystems.
What is confirmed and what is not
Confirmed: the 24 September date on all three platforms, the content counts above, the US$6.99 App Store price, the iOS size and version requirement, offline play, the existence of a Steam demo, the PC system requirements, and the 10-language support. Not yet confirmed: the Google Play price, Android device requirements, Australian pricing on any store, and the macOS price on Steam. This article will be updated when the Play and Steam Australia pricing can be read directly.
