Completed two MP adversarial mode games
 

I took convoy commander. All in it works quite well, a few small issues that makes controling the destroyers hard.

1 inability to set a rudder position for the selected ship, means a lot of thinking into which direction to set on the compass lol
2 when you bring up the binoculars you can put them back down, toggle doesn't work at all, so you have to switch ships and switch back again.
3 can't set a speed for the convoy, or direction. A good few times my convoy just sat in the water until attacked , then decided to bugger off !
4 no map keyboard command { as far as I can find }. means you spend some time switching via the mouse from bridge view to map with the icons, then back to ship contol section icons...
5 inability to stop the ships from shooting at the scope when it sees it...ruins the attack sometimes by alerting the sub to your approach..

apart from these small problems it was great fun. I managed to keep him away from the convoy, apart from one small passenger liner sunk and damage to a cruiser. I rammed him once and sunk myself, I did drop cans all over him as I went past but didn't damage him { bug maybe? } and later I did attack and can him as he crash dived.
No lag and no drops...two hours of fun :) You guys should give it a go!
