I already found a good control layout for mouse/keyboard on the demo.
The game may have been designed with a joypad in mind, but that doesn,t mean you can,t find your own good control scheme.
By the way, I,m half through the marine and predator campaigns and this game is awesome, seriously.
Also, you may have found some shutteing/freezing issues in the PC version as well as almost all people out there but those who own 2500€-3000€ rigs

. Tone graphics and resolution down and the game will run smoothly..., you know, I,m starting to think that textures on high work good only on directx11 this time. I,ve been trying lots of different graphical configurations yesterday and I can only come to that conclusion, plus the game seems to suffer from some heavy memory leaks if you use very high graphical settings. Tone then down and you,re done.
