Nightfall is the BBC’s first online multiplayer offering. Dreamt up in the world of sleep, players enter the game as they drift off, teaming up to defeat hordes of terrifying Nags and the nightmares they bring with them. 

Having developed the branding, digital agency MERó brought us on board to illustrate a set of characters and key heroes that would turn up throughout the game and its advertising. We’ve been sleeping soundly ever since.
