Hi!
I just finished my first mission and would be very happy for some feedback from you guys!

The mission is called "cleanup".
you will take command over a small special ops team with the objective to find and destroy vital targets in an insurgent controlled area. You will get to blow things up and ambush VIP targets.
Hope you enjoy it!
