This trophy is called "
There are many important moments in life, but this is not one of them" which requires you to clear all of the exhibition matches in the game.
This is a story based trophy and is unmissable.
When beginning the game, the user is forced through four training matches. Once all four are completed, then Story Battle (Mode) unlocks for the user. There are a total of five exhibition matches to complete and they're unable to be skipped as a cat sleeps on the road in front of the tank blocking progression until the newest battle is completed.
The breakdown of the story mode is as follows:
*** Spoiler - click to reveal ***0—Prologue - The plot of the game which takes place shortly after Girls und Panzer der Film. Essentially the Oarai school president wants to make a promotional video for tankery at Oarai. She invites every school that participated in the battles in GuP der Film to provide commentary and share battle information.
1—Exhibition Match: Oarai Golf Course (Hills) - The objective is to destroy one enemy tank. Just stay in position and peak over the top of the sand trap while aiming for the backends of the Matilda's.
This battle covers the opening of Girls und Panzer der Film where Darjeeling has fortified Gloriana's position in a sand trap against Chihatan and Oarai.
My playthrough:
2—Exhibition Match: Oarai Golf Course (Forest) - The objective is to defeat two tanks. You're in a defensive position on a small ridge as Pravda has arrived on the golf course to take advantage of Chihatan's recklessness. You should be able to defeat two tanks quite easily. This battle covers the second portions of the opening exhibition match in Girls und Panzer der Film immediately after Chihatan's rush into Gloriana.
My playthrough:
3—Exhibition Match: Oarai Town Hall - The objective is to destroy three enemy tanks. Erwin and Midoriko are waiting to ambush Pravda. They're pretty easy. Just shoot them in their sides as they appear. If playing as Nonna or Katyusha, you're in far stronger vehicles for the most part. Angle your tanks towards them and lay waste to them. This exhibition match covers roughly the middle of the opening battle from Girls und Panzer der Film.
My playthrough:
4—Exhibition Match: Oarai Streets - Each playable character has its own objective. Miho Nishizumi must reach a specific destination by following the marked path. This is a good time to learn the drifting mechanic instead of slowing down to make tight turns. As for Rosehip, you must destroy the Anglerfish tank to win. You can get a few shots off as Miho is running away, but after that, from the starting position, take the street left and drive two blocks and then block the street. Miho will drive right into you and you can prevent her progression towards the goal while chipping away at the Panzer IV's health. This exhibition match covers roughly the middle of the opening battle from Girls und Panzer der Film.
My playthrough:
5—Exhibition Match: Battle in Oarai Streets - All four characters have head to the destination as their objective. So, just follow the marked path. Once reaching the end, the objective becomes destroy opposing team's flag tank. No trickery or anything to it. Just standard shoot the enemy until they've been defeated. The battle covers the end of the exhibition battle at the start of Girls und Panzer der Film.
My playthrough:
Once the final exhibition match has been completed once, the trophy will unlock when reaching the Victory results screen.
