AI Summit: Branching Out: 'Watch Dogs Legion's' Architecture for Group AI Behaviours


In the open world of Watch Dogs: Legion, a key component of world tone is having believable AI performing realistic behaviours. While much can be accomplished using individuals, having multi-character interactions provides a richer experience. This talk will present in detail the aLiVE Group Behaviour System, a highly modular AI architecture developed at Ubisoft Toronto. This system allows for the creation of highly reactive group behaviours, used in Watch Dogs: Legion to author ID checks, extortions, crime events, hostage scenarios, protest groups, and police interactions. When the player interacts with these scenes, the group behaviour system can properly consider the group context and roles of participants to react in realistic and interesting ways.
