List of references to Marathon in the Destiny series

 * Tycho is a location in Destiny. An AI in Marathon is named likewise.
 * The Fate of All Fools gets its name from the phrase, "the just fate of fools," which the AI Durandal carves into a planet's surface in Latin after destroying Tycho.
 * The Duke MK.44 bears resemblance to the .44 Magnum.
 * Fusion rifles operate on a similar principle to the Zeus fusion pistol.
 * A patrol mission that can be obtained in areas where the Fallen roam is named "Low-Flying Defense Drones". "Beware of Low-Flying Defense Drones" is the name of a Marathon campaign level.
 * Manus Celer Dei is the name of the ship Durandal used to return to Earth in the second game. It also happens to be a player ship in Destiny.
 * The Almighty bears a striking conceptual resemblance to the Trih Xeem in which the pfhor empire uses as a last resort to quell revolts of subjugated races by igniting early supernovas.
 * The MIDA Mini-Tool lore tab appears to both reference and expand upon Marathons backstory. The MIDA-Mini-Tool lore tab features a first person narrative that references Battleroids and reveals that Bernard Strauss was able to salvage an ancient A.I construct from a ship that  crashed on Mars. Additionally the name MIDA itself is likely a reference to the MIDA revolutionary government that temporarily occupied Mars.
