Riot Games has released a new three-minute trailer showing and explaining a new game for their upcoming fighting game, Duo Play. The team explained how players will be able to play 1v1, 2v2, or 1v2 battles seamlessly, and that the game was being built from the ground up to allow that level of team play. Included in the video, the dev team also showed the Fuse system, which gives players the option to add certain enhancements to their characters or change fights.
