I'm enjoying it so far, although the interface is bloody complicated for a newbie like me. I've gotta press f to lock a target, except in certain situations it makes me talk to someone. I press the left mouse button to do one thing, but it turns out I'm in some special situation where it causes me to do something entirely different and ends up ******* off every soldier within a mile radius.
However, it's still good fun, and the graphics are shiny enough for me to forgive a lot of things.
