STAY ALIVE. STAY CONNECTED.
KCSN is a community leaderboard for Project Zomboid single-player survivors, built around persistent identities, live signals, ruleset-aware rankings, and permanent survivor history.
HOW IT WORKS
The Workshop mod records survivor statistics locally. The Windows companion authenticates and uploads those reports to KCSN. Cloudflare Workers validates requests and D1 stores persistent survivor history.
FAIR COMPETITION
Official Build 42.20 preset runs are separated from Custom Sandbox runs. KCSN also labels simulated network citizens clearly and excludes them from official player totals and records.
LEADERBOARD INTEGRITY
KCSN uses signed companion reports, replay protection, rate limits, impossible-stat validation, moderation flags, persistent character IDs, and permanent death records.
THE NETWORK
Every survivor gets a persistent record. Living signals compete on the leaderboard, custom runs remain visible in their own category, and deceased survivors are preserved in the Hall of the Dead.
