A resume from Crystal Dynamic's senior environmentalist Caleb Strauss includes an "Unannounced Project" involving his expertise.
Meanwhile, in Buzz Monkey town, the developers site lists that they're working on the "next smash success." Both studios brought Tomb Raider: Underworld to life, see where this is going?
It would be no surprise that team Crystal is working on the next instalment as they already done so much to bring Lara back from the brink of obscurity. Buzz Monkey handled the PS3, PS2 and Wii versions of Underworld but also has older Croft experience too.
Strauss' duties are "pre-production development, 3D world environment modeling, documentation, contribution to art pipeline and workflow, and mentoring." So sayeth the resume. Buzz Monkey meanwhile with news of a "Top Secret" game.
