Unturned: Gold Edition is developed and published by Smartly Dressed Games. It was released in 8 Jul, 2014.
Unturned is a sandbox game in the emerging multiplayer apocalypse survival genre. Rather than focusing on being an MMO it provides players with easy systems to sit down and survive the zombie infestation with their friends. Over the course of a typical adventure, groups will have a blast fortifying locations, scavenging for supplies, trying to live off the land and negotiating with other people. The game is being developed entirely with the community in focus, and tons of features are based entirely on feedback:
Fortification:
Players can build massive forts out of structural building blocks, or build onto smaller buildings in the world with barricades. It is also possible to create traps and intricate electronic systems. More options for building are constantly being added based on what the community requests.
