Development notes for Heartguard 3D and the Classic update archive.
Heartguard 3D
Introducing Heartguard 3D
The first teaser for the ground-up 3D remake.
Heartguard is being rebuilt from the ground up in 3D. The Heart Crystal, the waifus, and the kingdoms of Asteria return in the remake. Watch the coming-soon teaser, or join the conversation on Discord. Heartguard 3D is coming soon and does not have a playtest. A public release date has not been announced.
Replay audio and enemy inspection move closer to the live battle experience.
Classic’s replays now better match the sounds and enemy-inspection behavior of live battles. Return to a defense, study the enemies, and hear the action as you review the choices that shaped your run.
Classic / Update
Drag placement and Rankings updates
Drag waifus from the battle tray into position, and explore a refreshed Rankings page.
Place your squad with drag-to-place from the waifu tray. Alongside the battle-control update, Rankings has a refreshed presentation for browsing run records, with mode artwork for Endless and Gambit.
Classic / New mode
Stardust Gambit joins Classic
A new challenge joins Classic, unlocked after Hard Chapter 1.
Stardust Gambit adds another way to test your Heartguard. Unlock the mode after Hard Chapter 1, then return for a daily first-clear gem bonus and repeatable run rewards.
Classic / Endless
Endless arrives
Endless expands the watch beyond the campaign, alongside improvements to the Asteria atlas.
Classic’s Endless mode lets you take a defense further, one wave at a time. The campaign atlas also receives navigation improvements, making it easier to find your next kingdom and continue the journey.
Classic / Campaign
Campaign expands to 90 stages
The campaign rebuild brings 90 stages, Hard mastery objectives, and a new First Watch introduction.
Ninety stages, Hard mastery objectives, and verified rewards form the new journey, while First Watch and mastery missions help guide your next goal.
Classic / Early Access
Classic’s Early Access milestone
The beginning of Classic’s Early Access chapter, and the first day of its daily challenge calendar.
Invite-controlled access and deterministic Daily and Weekly challenges arrive in the original game, with loaner squads to help players face a shared challenge. September 4 marks day one of the daily calendar—and the Early Access milestone in this archive.
Classic’s archive is reconstructed from development milestones. Dates follow the project’s Pacific-time history; exact deployment times may differ. September 4 is the daily challenge calendar’s first day.
