Their constant fighting soon puts the whole project in jeopardy.To make matters worse, Yuuya comes to realize that Yukon Base is rife with international intrigue, as each nation tries to steal each other’s secrets and ensure that when the war against the BETA is over, they’ll be the ones with the most powerful weapons.
