[SPECIAL-INTERCEPTION] "ALTEISEN (Train)" FULL Clear [GODDESS OF VICTORY: NIKKE]
There are two neat tricks to help clear train. They requires either extreme skill, luck or gear so tread with caution.
First method is i-framing the twin turret, if you swap positions at the right moment, i-framing the turret is possible.
(Read my YouTube community guide for indepth i-frame guide)
Second method is leaving one of the turrets at low HP and destroying it as soon as it fires. this method works because of the weird mechanic the train has. The train, whether the twin turret shoots with 2 turret or 1 turret deals same damage. In both cases, your Nikke will most likely die. However, if you destroy one of the turrets as soon as they start firing, you can actually reduce the incoming damage by half. I am assuming the turret is programmed to do X amount of damage regardless of how many turrets there are, but you can fool the system by destroying one of the turrets as soon as it starts firing. Rest is straight forward, shoot red circle, shoot missile. GG
