How do I unlock rank 4 parts for the Gelgoog (Char)?

Clear the second mission of OYW Char Aznable's Official Mode (The Duel in Texas) on Hard difficulty and keep M'Quve alive until the end of the mission. This means that you must rush Amuro as soon as he appears and stop him from getting close to M'Quve -- once the two of them are near each other, a cutscene will play and M'Quve will die. More.

Unlock and clear the commemorative "40,000 Total Shot Down Enemies" (which counts totals for all pilots) Free Mission and read the terminal message received immediately afterwards. More.

Unlock and clear the "Crimson Lightning" Extra Mission. To unlock the mission, you must max out your relationship with Johnny Ridden and read the "You said alone was fine, right?" terminal message. That message is received after you clear the "Solo in Red 2" Collection Mission; to unlock the two "Solo in Red" Collection Missions, you must first clear the "Red Tri-stars?"

Collection Mission (which is unlocked if you've read the "Char's Past" terminal message sent after you clear the "Char's Offering" Friendship Mission and you've achieved a relationship rating of "Trust" or higher with Char, Kai, and Johnny). Note that the "Crimson Lightning" mission and both "Solo in Red" missions all require you to pilot a red mobile suit. More.

Unlock and clear the "Burn, Dragon" Extra Mission. To unlock the mission, you must clear Glemy Toto's Story Mode and shoot down 3000 or more enemies while playing as Glemy. This mission is playable for Glemy only, and it requires that you pilot the Bawoo.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
