Zero State Agent

You are OniOne, an elite covert operative dropped into the Canadian wilderness. Scavenge, build a base, and slip past the guards holding the valley. When stealth fails, fight your way out.

New to ZSA?

  1. Read Getting Started before your first night.
  2. Learn the Controls.
  3. Understand Detection & Visibility and Noise. Staying unseen is half the game.
  4. Chop Wood, mine Silicate, and set up a Crafting Table.
  5. Build a Bed so you respawn at your base, not at the drop point.

Latest update: v0.84

  • New Deer behaviour: they freeze, then decide whether to bolt.
  • Deer and Wolves now drop Hide. The Bed costs 40 Wood + 5 Hide.
  • Guards stay Heightened after a hunt and use cover. See Enemy Alert States.
  • Outpost alarms now bring in reinforcements. See Outposts & Alarms.
