Referring to the below PC Configuration screen for FRAGnStein, it is clearly illustrated that you can easily remove your keyboard as a primary WASD controller! No more aching left wrist and cramped fingers! We have been testing with many keyboard replacements in PC based fps games. This could be the next big way how PC based fps games can be played.
The really cool thing about FRAGnStein is that both the controller (Nuchuck) and Mouse can be used independently or together providing a high level of flexbility with your next fps session.
Of course this is only half of the immersive effects we are trying to build on our range of product offerings. Watch out for more details how we can further enhance fps games on PC platforms.
