I have been thinking alot about the latest hardest maps and I would like to give you some feedback how to approach them, so that you will find them more entertaining and perhaps would want to try the challenge of 1 life =).
These maps are Burgundy(Farmstead) - There is a wonderful way I just found out how to make it fast
and Burgundy(Broken Arrow). I made exact steps for you to follow in order for you to be able to complete the mission with 1 life. If you follow these steps and stay under cover, it is much more likely you could complete it with 1 life .
