This is for the achievement , for the the end game of sonic frontiers
You can get this achievement the so called harder way or the quick way
You get the achievement either way depending if you want a bit of a challenge 😁
Spoiler warning, the final boss is called The End its the voice that talks to you thought out the game telling you to destroy the titian and break the barrier between dimensions which are 6 tower that activate after you complete the third island (choas Island with tails)
The easiest solution on easy difficulty, instead of taking out the boss it puts you in a quick time event automatically where the titan /sage throws you into the planet called the end , you have a three meter on the screen net to super sonic where you have to press X into he gold spaces , after the cutscencss will just play out as normal to the credits
Now for the harder method, if playing on hard difficulty only, after the forth titan, they is another boss seques where you actually fight the end using the titian /sage and super sonic together, it is similar to the small game that you did when you get with the chaos emerald but a lot longer, you have to doge the bullets thrown at you by the end coloured in white or red , you use the RB and LB to switch to them coloures you can absorbe the colour you chose and you must keep shooting at the planet until Your meters at the bottom , is fully Gold the press RT to use super sonic dealing massive damage, once the boss health is gone. Just like easy difficulty you will gain the quick time event , completing the game , there is no extra cutscences to earn or watch , you just get pride.for actually defeating the boss its self
The achievement will unlock for both difficulty after super sonic smashes in the end boss,
I hope this confim s everything for everyone I will wite up the other achievements soon as I completed the game 100%
