Kingdom Rush 6: Genesis TD launches September 24 — Linirea’s past, Classic Mode, and five stage rulesets

Kingdom Rush 6: Genesis TD is out now. Ironhide Game Studio’s 24 September 2026 Games Press launch wire and the studio’s own “Out Now” site frame day-and-date availability on Steam, the App Store, and Google Play. Softcap’s first Genesis desk piece sticks to that launch primary, the live Steam store sheet, and Ironhide’s game page. Softcap is not inventing review-score averages beyond Steam’s live mixed tally, clear rates Softcap has not measured, or a roadmap Softcap cannot date from the Confirmed launch copy.

Primary spine: an original early-Linirea campaign (not a remake), the 15 / 12 / 9 towers–heroes–spells kit Softcap can cite from both the press wire and Steam About, Classic Mode’s 2011 arsenal lock, and the four alternate stage rulesets that rewrite how each map plays.

What Ironhide says ships today

The Montevideo studio’s Confirmed pitch is a time-portal story: the Sword of Elynie tears open a path into the Kingdom’s past, and players defend early Linirea while trying to stop a young Vez’nan before the corruption Softcap’s readers already know from earlier entries takes hold. Ironhide Community Manager Patricia is quoted on the Games Press wire calling Genesis a chance “to go back to where it all started, while creating something completely new” for veterans and first-timers alike.

Softcap’s Confirmed systems from the same wire + Steam About:

• Original campaign, not a remaster of the 2011 game — Softcap is treating “return to early Linirea” as setting/history framing, not a 1:1 remake claim.
• Synergy-first tower kit: bring five towers into a fight from the 15-tower pool (archers, mages, barracks, artillery and friends).
• Dual heroes: field two of 12 heroes per stage, with dedicated upgrade trees Softcap can cite for heroes and spells.
• Global tower upgrades that can be retuned between stages and reset at will.
• Nine spells; Steam’s Confirmed loadout language is equip three for the moments that matter.

Five ways Softcap can cite to clear a stage

Beyond the campaign clear, every stage unlocks alternate rules Softcap is treating as Confirmed from Games Press + Steam:

Mode	Softcap’s Confirmed rule
Classic Mode / Classic Rush	Complete with the original Kingdom Rush arsenal — Softcap cites eight classic towers, two iconic spells, one hero
Iron Challenge	One devastating elite wave · one life
Blitz Challenge	Three fast waves · quicker enemies · increased gold
Hero Party	Command four heroes · no spells
Spell Rush	No heroes · towers + faster-recharging spells only

Steam’s About block also flags 50+ achievements Softcap is citing as a Confirmed storefront line, not a Softcap clear-rate claim.

Price, platforms, and what Softcap is not inventing

Softcap’s Confirmed Steam US sheet at ship time: $19.99 list with a launch 10% discount to $17.99. The Games Press wire adds that the wider Kingdom Rush franchise is also on sale at “lowest prices ever” for the launch window — Softcap is not reprinting every SKU’s cut beyond that Confirmed framing.

Mobile is day-and-date with PC: Softcap’s Confirmed storefronts are the App Store and Google Play listings Ironhide published in the launch wire. Softcap is not inventing console ports Softcap cannot cite.

Collectible note (not Amazon): Ironhide’s 9 September Youtooz post and the launch wire both point to a limited Vez’nan vinyl on Youtooz, with orders Softcap cites as open through 15 October 2026. Softcap is not inventing an Amazon retail SKU for the digital game or the figure — no amazon.* / amzn.to buy path Softcap can confirm for this tick.

Post-launch content Softcap can cite without a dated calendar: Ironhide says development continues with additional stages, heroes, spells, and towers. Softcap is not inventing patch numbers or ship windows beyond that Confirmed “coming this year and beyond” language on Steam / the launch wire. Softcap also flags that the official site surfaces a Known Issues & Workarounds post Softcap has not transcribed into this launch card — treat that as a live ops page, not Softcap’s bug list.

Softcap’s takeaway

Genesis is Softcap’s Confirmed fifteenth-anniversary Kingdom Rush chapter: same Montevideo humor and handcrafted lanes, an early-Linirea campaign Softcap can cite as original rather than remastered, and a stage-mode menu that deliberately breaks the default twin-hero / three-spell loadout. If Softcap’s desk has one Confirmed first-session question from the launch sheet, it is which ruleset you open after the campaign clear — Classic’s 2011 lock, Iron’s one-life elite wave, or Hero Party’s four-hero / no-spell stack — not whether the series still knows how to put a tower on a path.
