Last year Marc Laidlaw published a Half-Life 2: Episode 3 synopsis. Named 'Epistle 3', it contained similarly-named, gender-swapped characters from HL2 and explored the ex-Valve writer's vision of what might have been. Speaking to our sister site GamesRadar, Half-Life 2 writer Chet Faliszek says he was "surprised" by his one-time colleague's decision to publish his ideas.   

"I'll let Marc speak for that," Faliszek tells GR. "I… I was surprised by it coming out. I'll let Marc speak for that."
