Behavior Interactive Inc. (stylized as bE HAVIOUR) is an independent Canadian developer based in Montreal, Quebec that developed Fallout Shelter.
Behavior Interactive is a game development studio originally founded in 1992 in Montreal, Québec, Canada by Remi Racine as Megatoon Entertainment Group. Two years later, Racine co-founded a Montreal-based Multimedia Interactive (MMI) to develop interactive entertainment software for CD-ROM. Both companies were sold to Malofilm Communications in 1996, and a year later, they were merged into Behavior Interactive. In 1999, Racine and some investors bought the studio back, but they had to rename it, changing the name in 2000 to Artificial Mind & Movement Inc. (A2M).
By 2010, the studio's name was reverted to Behavior Interactive, partly due to increased production of original titles and thus stronger presence in the gaming community. In June 2015, Bethesda Game Studios published Fallout Shelter, which was designed by Behaviour Interactive.
