The sequel to the Augmented Reality (AR) PSP game, Invizimals will come to North America this September. Shadow Zone will be presenting 100 new monsters into the game with an addition of a co-op option in capturing those pesky monsters hiding behind our colorful objects in the real world.
Invizimals: Shadow Zone is set to feature over 100 new creatues to collect, the ability to modify the Invizimals via name, and colour changes, as well as the ability to choose from a larger selection of attacks. Shadow Zone will also feature a new campaign, and a co-operative capture mode.
