Halo 4 developer 343 Industries announced today a number of changes to its staff, confirming that former LucasArts and Crystal Dynamics creative director Tim Longo has joined the company as its new creative director.

Outgoing creative director Josh Holmes, who worked on Halo 4, will take the role of executive producer and head up the internal development team. In a blog post on the 343 Industries website, Holmes said his new role will put him in charge of "overall project leadership and business ownership [and] setting the high level project vision and goals, and leading [his] team to achieve them."

Halo 4's executive producer Kiki Wolfkill remains with the company, but her new role is yet to be revealed. Holmes only wrote that Wolfkill's next project "is really cool" and that she is "developing exciting new stories, experiences and technologies that will transform the way that you experience Halo."

Art director Kenneth Scott is taking on a remote visual design consultant position, and Halo 4's lead concept artist Nicolas Bouvier will fill Scott's art directing shoes.

343 Industries isn't the only studio to welcome new staff in the new year. Microsoft Studios announced today that former Bungie Studios Halo writer and creative director Joe Staten joined the company to work on Xbox titles. A spokesperson for Microsoft said Staten will not be working on a Halo game.
