Oh, no... we recently went back to check on greenfield's status, and it isn't so green anymore. The enemy created a secret building, exactly where they had left their old base. It holds an entire arsenal, capable of destroying our entire unit. Luckily, they're in the process of fueling up their weapons. The fuel is explosive, so if you can blow their line, their fleet will be destroyed! There is a key to the base inside our old base. Good luck!
