Brothers: A Tale of Two Sons creator Josef Fares has said he is moving on to his next project, which will be "something special".
Speaking to Digital Spy at the video game BAFTAs, Fares said the idea is "definitely something that hasn't been done before".
"I can tell you this - if I tell you the idea now, you'd say, 'I haven't played something like this before'," he said, "I can't tell you more. But definitely something that hasn't been done before."
Fares indicated that the game may not be developed by Starbreeze Studios, which developed Brothers.
"Yeah, I think that's what's going to happen," he said when asked if the game will be made by his own studio.
"We'll see what happens... I can't talk too much about this."
In Brothers, players simultaneously control two siblings as they set out on a journey to find and bring back the 'Water of Life' to save their dying father.
Brothers: A Tale of Two Sons scooped the BAFTA Game Innovation award on Wednesday night. Here's the full list of video game BAFTA nominees and winners.
