Upgrade your wanzers (and remember that the wanzers with missiles and guns may need to upgrade their backpacks first before changing to FROST equipment or you may get weight overload). Then visit the Colloseum and you'll watch Gregorio , a big tough pilot beating some Adam Raen guy easily. You are given the choice of challenging him and you should say yes. Gregorio is a melee fighter, so watch out for his Stun attacks. He won't be much of a challenge if you upgraded everything to FROST though.

Gregorio automatically joins after your victory. You should take some time training on the Colloseum to get cash and upgrade your wanzers if you were low on cash before. Then go to the military office. Olson says that now with Freedom City recovered, it's time to go into USN territory. Your next mission is to see if it's possible to estabilish a base of operations in a small town called Lark Valley. You must go there and confirm if there are still USN units around. Head there and you'll find a completely destroyed town. Natalie explains that after the outbreak of the war, USN and OCU clashed exactly in this city. Lloyd feels guilty for a moment and a survivor called Maury shows up and tells you to get out. Shortly after, the USN arrives in the area and starts the attack.

Try to protect Maury, since she has that suicide tendency every guest character you need to protect has. It shouldn't be too hard, just don't let the carriers around for too long or the enemy wanzers will use it to repair themselves. After the victory, Maury is still enraged at you "army people" because you killed all the children and mothers of this city and she's the only one left. Lloyd tells her this war was caused by his actions. Strangely enough, Maury refuses to kill you and decides to tag along to see you burn with her own eyes (Whoa!). Now you can go back to Freedom City for your next mission
