How to Unlock All Endings in Ad Infinitum

This is a short guide to how you get each of the three different endings including their outcome.

Good Ending

To attain this ending, pursue the righteous path during all three boss encounters concluding each chapter.

Chapter 1

Utilize the three green-light music players in the confrontation against Despair. Then, initiate the button and engage with the creature to rescue her.

Chapter 2

Regulate the gas pressure by adjusting the valves situated in the four corners until all four lights on the central control panel turn green. Subsequently, activate the switch. Choose to save Corruption.

Chapter 3

Descend the three cages by pulling the levers downward. Maintain your position in the center until the battle concludes after successfully reacting to the creature’s assaults four consecutive times. Save Pain to conclude this chapter.

Outcome

This ending culminates in your reunion with family and the discovery of peace. Throughout the conflict, you come to terms with abandoning your brother amidst barbed wire and misinforming your family of his demise. Ultimately, your family recognizes the returning individual not as a monstrous entity but as your wounded brother.

Bad Ending

To achieve this ending, opt for the malevolent path in all three boss confrontations across the chapters.

Chapter 1

Activate the three red-light music players during the encounter with Despair. Proceed to engage with the monster, opting to eliminate her. Alternatively, defeat her and observe her being consumed by the void without intervening, resulting in a distinct achievement.

Chapter 2

Elevate the gas pressure by manipulating the valves in the four corners until all four lights on the central control panel turn red. Then, activate the switch. Elect to kill Corruption instantly or observe his demise for an alternate achievement.

Chapter 3

Raise the three cages by pulling the levers upward. Remain stationary in the center until the confrontation ceases after successfully countering the creature’s assaults four times consecutively. Choose to kill Pain or await his demise for another achievement.

Outcome

This ending unfolds with the discovery of the deceased bodies of all three family members, with you being accused of their murders. The officer rewards you and consigns you back to the battlefield, seemingly ensnared in an endless cycle.

Worst Ending

To attain this ending, make mixed choices during the boss encounters, saving some bosses while killing others.

Outcome

In this conclusion, discover the deceased bodies of some family members while others find redemption based on your choices during the boss fights. Ultimately, the officer appears, condemning you, claiming there’s no such thing as partial victory. You find yourself confined to an asylum, haunted by the specters of the monsters representing your family members.
