Players with a premium account on the browser-based iteration of the game could begin playing before its official release into early access on July 7, 2014. On June 17, 2014, a new major iteration of the game was brought onto Steam.

The browser game continued to see development until 2014.

Unturned first began in 2013 as a browser game, and was created as the spiritual successor to Deadzone. The desktop version of the Unturned is the most extensive and updated version of the game. Unlike its first two iterations, version 3 features Steam Economy integration in the form of random daily playtime drops, a Community Market, and a developer-managed storefront called the Stockpile. The game is available from its store page, and community features can be easily found through its community hub. The game has gone through three distinct iterations: 'antique,' 'classic,' and 'version 3.' A 'preview' branch can be opted into that allows for public testing before an update goes live, and previous engine versions of the game are available as separate branches for archiving. The latest iteration of Unturned is developed in the Unity game engine. Unturned is a free-to-play post-apocalyptic zombie survival game developed by Smartly Dressed Games, and originally started as a browser game before moving to Steam.
