Local co-op coming in The Binding of Isaac‘s remake may sound jolly exciting but are you concerned that having help might turn the roguelike-like into a game for, not just about, babies? Relax! Take a chill pill, pal. Designer Edmund McMillen has explained how it’ll all work and, from the sound of things, Rebirth’s co-op will bring the joys of friendship without necessarily losing the thrills of trying not to die. See, calling in a baby friend (no, co-op players actually are babies) will cost a slice of your life, and they may come with a terrible curse.
