The big picture
Some secret organizations destabilize governments. ANTHEM#9 has its agents sort colored gems until somebody takes an alarming amount of damage. It's an admirably transparent operating procedure: if the mission goes badly, the paperwork can simply say that everyone involved needed more green. Developer koeda turns that unlikely premise into a single-player roguelite built around matching gems, arranging skills and coaxing separate decisions into one extravagant combo. The espionage theme provides an excuse for the violence, while the board handles the actual diplomacy.
The Windows PC release belongs to February 2026: Steam displays February 4, while Shueisha Games dates its launch February 5. Earlier demonstrations were demos, rather than a commercial Early Access release. Those calendar labels matter less to the appeal than the central invitation: construct an attack sequence so neatly that your enemies effectively lose an argument with your filing system.
Reasons to look closer
The interesting wrinkle is the connection between your deck and the gems that power it. Skills aren't merely prizes to collect because their numbers look muscular. Their requirements affect how comfortably they fit into your developing machine. Customizing those color requirements gives deckbuilding a practical, almost domestic quality. You've bought the impressive new appliance; now you need to discover whether anything in the kitchen can supply it with electricity.
That makes the puzzle more personal than matching whatever happens to land in front of you. You're preparing the conditions for future combinations, then deciding how to exploit them when a battle begins. A coherent collection of skills offers a plan you can recognize. An untidy one offers several exciting possibilities and the organizational standards of a drawer full of unidentified charging cables. The satisfaction lies in bringing intention to that mess, rather than simply accumulating more stuff.
The game's willingness to marry preparation with execution gives it a clear audience. If you enjoy building systems but also want to press the button that makes them behave outrageously, this is a sensible place to look. The deck supplies your argument; the combo supplies the unnecessarily emphatic punctuation.
The clock has an off switch
ANTHEM#9 originally placed considerable emphasis on assembling combos within a limited window. That introduces a lively tension between knowing what would be clever and managing to do it before the game politely closes the suggestion box. Planning and quick recognition become partners, although partners who may occasionally blame each other after a failed meeting.
Crucially, the March 20 update added a timer-free mode. Treating speed as an unavoidable requirement would miss a substantial part of the current game's appeal. Removing the clock lets the puzzle breathe for players who prefer to inspect their choices without also negotiating with a countdown. It's a welcome distinction between a demanding decision and a hurried decision. Those can produce very different kinds of enjoyment, even when the gems are wearing exactly the same colors.
After the standard missions
Clearing Missions 1 through 4 unlocks Extra Mission challenges, with successive stages strengthening enemies and adding restrictions. This is the point where a decent combination is invited back for further questioning. For players who enjoy refining a system against increasingly awkward conditions, that structure gives the deckbuilding somewhere to go after basic familiarity sets in.
The May update also expanded the available skills, Blessings and charms. More options make the most sense here when they encourage fresh combinations, rather than turning the collection into a museum of objects you refuse to use. ANTHEM#9's strongest idea is the relationship between the pieces, and its longer-term appeal depends on whether that relationship keeps you curious.
The verdict
ANTHEM#9 is an inviting proposition for puzzle-minded roguelite fans who enjoy making a plan, adjusting it and then watching several modest choices develop unreasonable ambitions. Its character-specific tricks and timer-free option give that proposition useful range. Anyone seeking a grand espionage drama should keep expectations centered on the systems. This organization settles global affairs through gem management, and the most important confidential document is probably your next combo.
