Every ZSA world is a mountain valley generated from a seed. The same seed always builds the same valley, so you can share good seeds with friends.
Landscape
The valley is roughly 3 km across and ringed by mountains, with bigger peaks looming beyond them. Inside you'll find several Biomes, swimmable lakes and ponds, and rivers with rapids. Roads link the outposts, crossing rivers on bridges or at fords.
Arrival
Each new game opens with a fly-in: the camera drops down out of the sky onto your drop point.
Points of interest
The valley is scattered with small sites and fortified outposts. See Sites and Outposts & Alarms.
A world that remembers
Trees you fell, rocks you mine, guards you kill and loot you take stay gone in that world. Plan your resource runs with that in mind.
