I downloaded the beta from Steam and tried the game. The controls were fine in AVWW1 and now they STREAMLINED them.
To "balance" things they ditched the mouse support in the game. Haha. Just keyboard or gamepad. The mouse can only be used in the options menu.
Edit: A somewhat strange explanation why there is no mous support. http://www.arcengames.com/forums/ind...ljf2m9rgg7e5v1
