Here’s the portion of Bruner’s letter to Telltale Games Staff in which he announces his resignation:

Bruner will be leaving his position at Telltale mid-way through releasing the third season of The Walking Dead, with plans to release a season of Guardians of the Galaxy later this year. There are also likely numerous projects in various phases of production - Telltale typically has at least a few episodic series going at a time.

Bruner’s departure was later confirmed by Telltale communications guru Job Stauffer, who provided the following prepared statement:

Prior to taking on the role of CEO at Telltale in 2015, Bruner served as the company’s CTO. Before Telltale, Bruner was a Lead Programmer at LucasArts where he worked on games like Grim Fandango, Monkey Island, and ultimately a Sam & Max sequel that was canceled and led to the formation of Telltale.

Bruner played a key role in the development and growth of adventure games over the past two decades and will hopefully continue to in the future as he steps down as Telltale CEO today.
