Ok first thing I need to say it WOW this is awesome!!, I didn't even know someone was remaking Renegade. Its fantastic.
anyway
I am having a very strange bug where I can use my mouse to navigate the menus in the game like setting up a game and changing my controls but when I get into the game I can still shoot (LMB) and aim (RMB) but I cannot move my camera around at all. WSAD still walks me around but I just cant move my camera with the mouse, then when I hit esc my mouse works in the menu (or help thingy).
I can also play it with my xbox 360 controller fine (however down on the d pad ragdolls me) I have tried with steam running, without steam, with xbox controller plugged in, unplugged. I just cant get my mouse to play the game and its a dam shame because what little I played with my xbox control I really enjoyed it.
