Unturned Server Hosting
Unturned is a free-to-play sandbox style game for the PC available through Steam to download with premium DLC available too. You start alone or with a group of other survivors tasked with defending yourselves from the zombie infestation that is coming your way. Much like Minecraft and other sandbox survival games you can craft tools and build bases to improve your chances of survival.
A dedicated server for Unturned allows the games host/s to play without worries of reducing there own gameplay experience. A few hosts have started offering servers for the game but due to its infancy the list on this page has a good scope for growth as the game gains more players.
