Ubisoft announced two new modes for Assassin’s Creed Odyssey today: a Story Creator Mode and a Discovery Tour.
Story Creator Mode is a free quest-creation tool that is starting its open beta today. It allows players to create their own stories and play quests created by other players. Quests made in the mode are available cross-platform on PC, PS4 and Xbox One.
Based on the story-designer tools and branching dialogue systems used in Odyssey, it lets players write their own stories accompanied by gameplay. Players can mix and match six quest objectives, like freeing or assassinating targets and going to specific locations. They can create branching narratives with multiple outcomes, and have access to several historical characters from the game to retell historical events. Players can also define role-play options in the dialogue system, which includes lying to or attacking NPCs.
