Hey all, thanks for supporting m07games and GunWorld 2!
I just wanted to mention that I've been alerted to some issues that have been affecting users who play the game with a keyboard as opposed to a controller.
I've released about 3 updates so far to fix the control interface to make keyboard's work as flawlessly as controllers, and I have a 4th coming out tonight. I apologize for the inconvenience, but after tonight's update keyboards should work perfect!
I plan on adding a keyboard controls sheet to the pause menu in a future update, and updating all text during the tutorial to give you both the controller and keyboard inputs for each function.
