フィニッシュドライヴ！完全版！ Trophy in VVVtunia
How to unlock フィニッシュドライヴ！完全版！[Finish Drive! Complete Version!]
[A pursuit of the Finish Drive broke out for the first time.]
For this trophy, you need to perform two Finish Drives in a single Resonance Mode such that the second one has an extra bit compared to the first one.
To enter Resonance Mode, you must get your Sound Gauge (located on the left side of the screen) all the way down to your side and watch for when the game prompts you that Resonance Mode is available. You can tell this as there is some text near the bottom of the sound gauge that says RESONANCE MODE on it. Once you can enter Resonance Mode, press to do so and you will be in it for the rest of the current song.
Once you are in Resonance Mode, you can activate Finish Drive using the same method of bringing the Sound Gauge down. You will get a prompt to activate Finish Drive in the same location as the initial Resonance Mode prompt. Once this is up, press again to unleash a Finish Drive.
While this may seem annoying to do at first since you will start off not being able to activate Resonance Mode until pretty late into a song and it can take a while for your Finish Drive to be ready, this will get much easier later in the game as you level up and it becomes easier to bring down the Sound Gauge. It is likely that as long as you are actively using Resonance Mode and Finish Drive, you will get this naturally later in the game.
