I've just uploaded the first update to Firefight. The big change is that at the end of a mission you get a summary dialog box appearing which lets you know your performance and you get a rating of how well you did from zero to three stars.

There are lots of other new features too like you can click on a radio message and the screen will jump to where that action occurred, the mouse cursor shows the height of the terrain underneath it, when you tell a squad to fire the mouse cursor shows the distance to the target and mortars show where they are currently doing a fire mission at.

There was also a bad bug which meant that enemy tanks and anti-tank guns sometimes could know where your tanks were if you tried sneaking around their flanks, and could turn to face you. It should be much easier now to sneak around the enemy and catch them unawares.
