ZERO DAY
Sign in
// EARLY ACCESS

Build a deck. Hack the opponent.

A free online card game with a cyberpunk twist. Your deck is hardware, programs, hacks, and exploits — start with the tutorial, work through the campaign, then take what you build online when you're ready.

Heads up — Zero Day is in early testing. Things will change, balance will shift, and you might hit a rough edge. We'd love your feedback while we polish.

// WHAT'S INSIDE

Plenty to do beyond the ladder.

Build your collection

150+ cards across hardware, programs, hacks, and exploits. Open packs to find new ones, craft what you're missing, and tune each deck for a different matchup.

Lots of ways to play

Learn in the tutorial. Work through the campaign against scripted opponents. Run quick matches against the AI when you want to test an idea. Play live games against real people when you're ready.

Always more to earn

Ranked seasons with cosmetic rewards. A battle pass that ticks up as you play. New cards, alt-art, and unlockables that follow you match to match. Your rank resets each season — your collection stays.

Ready when you are.

Free to play. No download — runs in your browser on any device, and your collection follows you wherever you sign in.
