Endeavor One is a Seattle based VR company focused on entertainment based experiences and social gaming.
Endeavor One is a small powerhouse studio with ties to the Halo series. Its co-founder, Tom Doyle, was the former lead artist at Bungie Studios. After more than a decade of working for Bungie, Doyle left to start-up Endeavor One with Sherry Floyd, along with other artists, designers and engineers that hailed from Bungie, Warner Brothers, Sony, and Valve.
The company's first VR project, Jump, a large scale first-person jumping puzzle game, was released on SteamVR in the summer of 2015.
Endeavor One later partnered with Microsoft Studios and 343 Industries to bring Halo Recruit to life for Windows Mixed Reality.
