We know 2K Marin is hard at work on their (somewhat belated) FPS adaptation of XCOM, but that might not be all they've got up their collective sleeve.
According to the resume of studio co-founder J.R. Hogarth de la Plante, an internal team is also hard at work building a brand new IP for 2K Games.
"I’m currently an Art Director on a 5-person director team responsible for defining a new IP for 2K Games based out of the 2K Marin development studio," the resume reads. "I have been creating high-level art direction documentation, executive-level summaries, technical documents related to middleware engine evaluation, managing external concept artists, and building world prototypes for performance/creative evaluation."
From the sound of things, work on the project is still in its earliest stages. Even if 2K greenlights the project, it'll likely be years before we here anything concrete.
Given Hogarth de la Plante's backround, though, it's hard not to be a little excited at the prospect of something new. Prior to founding 2K Marin, he worked as a level architect on the original BioShock and as lead environment artist on the sequel.
