Steam Early Access game Earth: Year 2066 has been pulled from the digital store following a community backlash over false marketing.
Earth: Year 2066 is described as a "first person sci-fi apocalyptic open-world game where your main aim is to survive". But according to numerous user complaints, the game, which was released in April following a successful round of voting via Steam Greenlight, suffered severe glitches that made it largely unplayable, and featured allegedly stolen assets including art and music.
It was also claimed that the game's developer was editing user comments, turning negative posts into positive ones forcefully.
Valve has acknowledged the controversy by removing the option to by the game on the Steam store, and offering unhappy buyers a full refund on its $19.99 price.
"On Steam, developers make their own decisions about promotion, features, pricing and publication. However, Steam does require honesty from developers in the marketing of their games," said Valve in an official statement.
"We have removed Earth: Year 2066 from Early Access on Steam. Customers who purchased the game will be able to get a refund on the store page until Monday May 19th," it added.
This isn't the first time Valve has pulled a game from Steam - survival horror MMO The War Z was taken down under similar circumstances in December 2012. That game was re-introduced to Steam in February 2013 after developer Hammerpoint collaborated with Valve to address the game's issues.
The War Z was later renamed Infestation: Survivor Stories following a copyright dispute.
