About Greyline
Nobody Is Coming
Greyline is a hardcore multiplayer survival game. You wake up with nothing and one goal: stay alive. No quests, no one telling you where to go. What happens next is up to you.
Why Greyline?
Out here, nothing is black and white. Every survivor walks the grey line between helping and taking, trusting and shooting first. Which side you end up on is your call.
No Markers, No Hand-Holding
No quest arrows, no minimap. Find your way with a compass and what you remember of the roads. Everything you need has to be found, and the next house might have nothing in it at all.
Calder Island
The first of many maps. Farms, towns, forests and military bases, and a base buried in snow high in the mountains. When night falls it gets truly dark, and your light is the first thing anyone sees.
Stay Alive
Hunger, thirst and cold will wear you down. Get hurt and you'll bleed, limp or black out. Patch yourself up with whatever you've found and hope it's enough.
The Infected
The outbreak got here first. The infected crowd the towns and bases, and one gunshot can bring a whole street down on you. Sometimes the smartest move is not to fight at all.
Friend or Foe
Up to 80 players share the server with you. Some will help you up when you go down. Some will want your boots.
Gear That Matters
Every gun, every round and every piece of kit was looted, fought for or taken from someone else. You can lose all of it in a second.
One Developer. His Free Time.
Greyline is made entirely by one person, in his free time. No studio, no publisher, no team behind the curtain. Just one guy building the survival game he wants to play. It's Early Access, so expect rough edges, and expect it to keep getting better. Jump in now and you're one of the first people to set foot on the island.
It won't be easy. Nobody is coming. This is Greyline.
