Sega has teamed up with Kuju Brighton to develop new title Crush for the PSP.
The game is due for release this summer, and promises a gameplay mechanic whereby players are able to change the environment from 3D to 2D, in order to solve puzzles.
"Crush introduces a fascinating new gameplay perspective on the PSP that encourages players to stretch their imagination in a whole new way," said Scott Steinberg, VP of marketing for Sega of America.
"The spatial concept of the crushing mechanic is something truly unique that encourages users to think back and forth between 3D and 2D objects and environments to engage different parts of their brain, and see beyond what is literally in front them."
