1. Single player, restart button. After I successfully complete a mission, there is no chance to restart it. Only exit, and continue. I love the Spartanovka stages, so I play them repeatedly. But I have to push exit, then wait for the loading, again and again. If I press Esc, there is a Restart mission, without loading, but the summary won't disappear, so I can't play the scenario again.

2. In real life, bullets can penetrate thin wooden fence. I fired an entire magazine in the fence, but the soldier behind it stood up, and shooted me.

The fence doesn't even looked damaged. I think it's not even a bit realistic, that a 1-2 cm thin wooden plank will save me from a burst. And will take it without being damaged. Or it's just in single player? Maybe you can adopt from the Brothers in Arms Hell's Highway. I think it's uses Unreal Engine 3 too. And there the light covers can be destroyed.
3. Maybe the weapon statistics can be tracked in single player too, because I use that gun, so I master it in that time too. I don't like multiplayer, so I can't get a bayonet, or drum mag, or silencer? Thats a little discrimnative, I think.

If I came up with anything else, I will let you know. Thanks for your time, and thanks for the game.
