Brothers: A Tale of Two Sons should be played with a controller on PC, the game's creative director has said.
Josef Fares warned against playing with mouse and keyboard for the downloadable adventure game, which sees the player control two brothers with a single controller.
"We're going to put a big warning sign on Steam that says please play on a controller, because the main thing is the controller," he told Digital Spy.
"You can play with a keyboard but that would destroy everything with the game. It's really extremely important that you use a controller."
An additional warning will also be displayed as the game starts asking for players to use a control pad.
