Winter starts on Tuesday, “Game of Thrones” fans. That’s when you’ll be able to pick up a sword and join House Forrester as it attempts to save itself from an almost certain doom. Telltale Games has announced that “Iron from Ice,” the first episode of the company’s six-episode “Game of Thrones” video game, will launch on Tuesday for both PCs and the PlayStation 4 console. “Iron from Ice” will be available on Xbox One, Xbox 360 and European PlayStation 4 consoles on Wednesday, followed by an iOS release on Thursday and PS3 releases on December 9 and 10 for North America and Europe, respectively. An Android release is coming later in December.
