Valve has stopped sales of The War Z on Steam in response to overwhelming fan criticism.
Claims of "Misleading advertising", forum censorship, and controversial microtransactions have surrounded the game since Monday's release.
The zombie survival game's Steam page is still up, but the game cannot be purchased.
Customers can still buy through the official website.
Valve has gone so far as to issue unhappy customers a full refund of the game.
"From time to time a mistake can be made and one was made by prematurely issuing a copy of War Z for sale via Steam," Valve told Kotaku.
"We apologize for this and have temporary removed the sale offering of the title until we have time to work with the developer and have confidence in a new build."
"Those who purchase the game and wish to continue playing it via Steam may do so. Those who purchased the title via Steam and are unhappy with what they received may seek a refund by creating a ticket at our support site here."
