The release date is locked in.
BLACK STACK launches August 30, 2026 on Steam for Windows and macOS.
BLACK STACK is a cyber-occult roguelite deckbuilder about breaching a sentient corporate megastructure. Build your deck from 496 playable protocols, choose between three distinct identities, and fight through two connected campaigns.
Powerful actions generate Trace, representing the evidence you leave behind. The stronger and more aggressive your build becomes, the more violently the Stack begins responding to your presence.
Launch pricing
The standard price will be $8.99 USD, with regional pricing applied by Steam.
BLACK STACK will be 10% off for the first seven calendar days after release, giving everyone a chance to enter the Stack at the launch-week discount.
One game. One purchase.
There are no microtransactions or additional purchases.
BLACK STACK includes a free battle pass progression track, with every reward earned entirely through play. One purchase includes the complete game.
