I believe I can fly is an achievement exclusive to Agony UNRATED.
Achieve requirement[]
Beat the Succubus Mode for the second time with the total killing number of 30 infants. This will unlock the "Queen Ending", the second part of the game's true ending.
Notes[]
- The achievement's title is possibly a reference to the 1996 "I Believe I Can Fly" song written by the American songwriter and singer R. Kelly. Either if this is coincidental or not is unknown.
