Surface to depth
From the surface hold you choose a rift and begin the breach. Stamina runs down with every step. Extract while you still can, or collapse and wake on the surface with what you kept in the vault.

Learn more →What is Breachwalker?
Breachwalker is a web-first expedition survival game from Benum Labs. You stand on the surface hold, select a rift from the ledger, and breach inward — managing stamina, fighting through procedurally derived space, and deciding when to extract loot to your vault.
Rifts are seeded from Bitcoin's public on-chain history, so two catalog entries can feel radically different in danger and scale. The closed alpha tests whether that loop is worth returning to before marketplace trade and item NFTs on Base join the picture.

Roadmap
Alpha now. Item NFTs on Base later.
Closed alpha is off-chain — no wallet. Planned: marketplace settlement in Strikes, utility-first item NFTs via asset bridge on Base, Coinbase Wallet onboarding, and sponsored minting we are exploring for first-time bridge-out.
Walk the breach first
Closed alpha testers will breach early rifts, stress the extract loop, and shape what ships next.
