Like the Final Destination stages, this field was never purposefully programmed into the Prototype; unlike Final Destination, however, this stage's presence may be more serendipitous than anything. As a testing ground of the Prototype, the doctors are able to train and battle against the data of opponents they've faced in their travels, within the infinite variables of the Prototype's capabilities and confines. Altogether then, it's the perfect battle simulator to iron the steel of your armies, and to continue to push the boundaries of your strength! After a long and hard-fought quest, a little training might be fun!
