Sonic Frontiers Secret Ending + Boss Fights

Learn how to unlock the Secret Ending and The Secret Boss in Sonic Frontiers.

The plot of Sonic Frontiers does a fantastic job of connecting most of its cliffhangers and answering the early riddles that propel it ahead. But gamers who received the standard ending will have noticed it closes on something of a somber note for a particular character. In our Sonic Frontiers Secret Guide, we’ll tell you everything about the Secret ending and the Secret Boss.

Key Highlights

To unlock Sonic Frontiers’ secret ending:

  • Play in hard mode.
  • Encounter final boss “The End,” exclusive to hard difficulty.
  • Defeat boss “Supreme” and enter top-down shooter mode to defeat “The End.”
  • Focus on Supreme’s face, dodge attacks, and manage increasing difficulty.
  • “The End” is a space-consuming creature.
  • Easy/normal modes require Quick-time event completion; hard mode adds an extra challenge.
  • Control Supreme in space during final boss battle.

To unlock the secret ending, follow these steps:

  1. Play on Hard Mode: The secret ending is only accessible in Hard mode. You cannot encounter the true final boss or unlock the secret ending on Normal difficulty or below.
  2. Difficulty Adjustment: If you find it challenging to complete the game on Hard, don’t worry. You can change the difficulty setting just before the second boss battle begins.
  3. Defeat Supreme: In Hard mode, you’ll face the Titan known as “Supreme.” Overcome this boss by avoiding its ranged attacks and bullet hell-style attack patterns. This is part of completing the game normally.
  4. Battle “The End”: After defeating Supreme, Sonic and Sage will travel into space to confront the true ancient evil known as “The End.” The gameplay mode changes to a top-down shooter style, similar to earlier hacking sequences but with increased difficulty.
  5. Overcome “The End”: During this battle, The End will fire powerful laser beams that cannot be stopped by bullets. Successfully defeat The End by skillfully navigating and using Quick-Time Events (QTEs) when prompted.
  6. Achieve Victory: If you manage to defeat The End and successfully complete the QTEs afterward, you will unlock the secret ending.

In the secret ending, you’ll witness Sonic and Sage’s encounter with The End, and the story will take a unique turn. Enjoy the additional narrative content and the conclusion to the game’s true story.

The Eggman will now give Sonic the last Chaos Emerald that he needs to activate his Super Sonic powers. And Sonic will then sprint out to battle this massive, antiquated foe.

Many players may find it to be a terrifying battle, yet there is a reliable strategy for defeating this titan. Here is a strategy for defeating Supreme and the last secret boss beyond.

Beating Supreme:

  1. Focus on Supreme’s face and deliver powerful combinations.
  2. Be prepared to block Supreme’s 360-degree slicing attack when signaled by a light flash.
  3. Avoid Supreme’s multiple minor attacks and focus on delivering your own strikes.
  4. When Supreme’s health is reduced to half, expect a challenging phase with moving mines and monsters.
  5. Carve a safe path across the mines to get close enough to damage Supreme.
  6. When Supreme has no more health, complete a Quick-time event (QTE) to avoid the final shot and end the battle.

“The End” Boss:

  1. In easy or normal modes, complete a QTE to defeat “The End.”
  2. In hard mode, control Supreme in space and match the colors of your shots to block The End’s attacks.
  3. Use the left bumper for White-Light Shots and the right bumper for Red-Dark Shots.
  4. Build up the laser attack meter by matching colors to block attacks.
  5. Use the right trigger to launch a homing laser strike when the meter is fully charged.
  6. Continuously fire at The End, alternating between colors to match its attacks.
  7. Watch out for combination attacks that combine Light and Dark Shots.
  8. Evade red lasers that limit your mobility by moving to the sides.
  9. Dodge The End’s powerful center laser blast by running to the side.
  10. Continue dodging, shooting, and using the homing laser until you defeat The End.

By following these strategies, you can successfully defeat Supreme and “The End” in the game and progress through the story.

Secret Ending Unlocked

After the end credits have finished, players may see an additional sequence that reveals Doctor Eggman has successfully restored Sage inside the computer systems and has rescued her. This scene can only be seen by completing the True Ending.

The End is a horrific space creature that engulfs worlds. And Sage presumably dies, striking the final blow in the Secret Ending. Sage’s progress during the span of the storyline finally leads to her teaming up with Sonic to battle against it. The fight’s outcome leaves her condition unclear, but the expected conclusion strongly suggests that she died.

Nothing throughout the game alerts you that your choice of difficulty will alter the final boss battle. Instead, The Secret Ending has been found by Sonic Frontiers players who began playing the game shortly after it launched and have rapidly finished the 20-hour campaign.

Fans soon recognized that they were discussing different final boss encounters, which suggested that they had engaged in completely distinct conflicts.

The End is the real last boss, and defeating him requires much more firepower and fast thinking. The End strikes you hard throughout the encounter, making it more difficult than the previous earlier-game bullet hell sequences.
