Jjaro

After multiple instances of these "jumps", the player (seemingly the only being who realizes he is being transported between possible realities) activates the ancient Jjaro station, preventing the chaotic entity's release. The ending screen of Infinity leaves the story's resolution open-ended, taking place billions of years after the events of Marathon Infinity.

Despite the player’s being teleported to a Jjaro station by Durandal and left with a grim message in the beginning of Infinity, both Durandal and Earth did survive in the original timeline as can be seen at the end of Marathon 2.
