Split Fiction is Hazelight's third co-op exclusive game, preceded by A Way Out and It Takes Two. This talk explores how the gimmick of Split Fiction's final level turned out to be the largest co-op design challenge so far, and why its unique concept was saved for the end of the game.

Designer Hannes Gille dives into the obstacles, and respective solutions that were discovered when designing this dual-world level. Different techniques were used to promote communication, collaboration and to create jaw dropping moments. The presenter walks through the design strategy used to reveal the concept, how the ingredients to make satisfying co-op puzzles were discovered, and why simplifying the design can give the players more room to be blown away.
