It's as if Daniel Steger, the designer of Mount Your Friends, saw those overly snug underpants in PUBG and said, "Hold my beer."
Mount Your Friends, released in 2014, was a gleefully silly multiplayer game about muscular pinheads clambering over each other in speedos with their physics-enabled wangs wobbling about. It's just had a sequel announced, called Mount Your Friends 3D: A Hard Man is Good to Climb. It looks every bit as ridiculous and, yes, it still has huge flappy wiggling dongs in it.
According to the trailer it's coming to Steam in 2018. Can't wait.
