quote Riukken

I am stuck on Green Earth the one mission I hate. I forget its name but you have to rescue Sami from Adder. I am playing hard campaign too.

You must be very careful in the mission, just aim for destroying the laser cannons ASAP, it is much more important to destroy the laser cannons than in normal campaign becuase you WILL get overwhelmed unless you are getting all S ranks in hard campaign.
