Rumour has it that Canadian studio United Front Games have closed down with a great suddenness. They’re best known for open-world crime simulator Sleeping Dogs, and most recently took multiplayer futurecrime brawler Smash+Grab to Steam Early Access. United Front haven’t formally announced anything yet, but scattered tweets and whispers suggest they’re done for. Smash+Grab has been pulled from sale too. Heck, this is mighty sudden – S+G held a free trial only last weekend. Hurling a brick as a Hail Mary pass.
