How do I unlock rank 4 parts for the Hambrabi?
Unlock and clear the “Yazan’s Strike Force is Immortal!” Extra Mission and read the terminal message received immediately afterwards. To unlock the mission, you must have cleared both “The Fourth Yazan Crewman” Free Missions and tally 3000 or more enemies shot down while piloting the Hambrabi (combined total for all pilots). The “The Fourth Yazan Crewman” Free Missions are unlocked after you clear the “Cold Machiavellian” Friendship Mission. Both “The Fourth Yazan Crewman” missions and the “Yazan’s Strike Force is Immortal” mission require you to pilot the Hambrabi only.
