Halo Universe

 * The Plasma Pistol is much like the Fusion Pistol from the Marathon series, which also shares a vibrating overcharge shot.

Halo: Combat Evolved

 * The campaign begins with John-117 awakening from cryo sleep after a massive battle much like it did in the beginning Marathon 2: Durandal, where the Protagonist woke up after cryo sleep from a massive battle.
 * Carol Rawley, call sign "Foehammer" is named after a level in Marathon: Infinity called "Foe Hammer".
 * Marathon 2: Durandal has a level named "If I Had a Rocket Launcher, I'd Make Somebody Pay," Halo: Combat Evolved has a chapter called "If I Had a Super Weapon..." in the campaign level Assault on the Control Room.

Halo 2

 * In the opening cinematic of the level Cairo Station, Fleet Admiral Terrence Hood mentions the "United Earth Space Corps," Marathon features the Unified Earth Space Council, and both of them share the UESC acronym.
 * The Elite rebellion against the Covenant parallels similar events in the Marathon series. In Marathon, Durandal convinced a group of S'pht to rise up against the Pfhor who enslaved them; and after Durandal's disappearance in Marathon 2, the rebel S'pht found themselves stranded together with a group of humans on a hostile world (similar to the Elites' predicament on Delta Halo).
 * The player's main goal in Halo 2 is to stop the Covenant from inadvertently destroying all life in the galaxy with the Halo installations; in Marathon Infinity, it was to prevent the Pfhor from inadvertently releasing a galaxy-destroying chaos being.
 * There is a chapter in campaign level The Great Journey named "Delusions and Grandeur". Marathon Infinity has a network level named "Delusions of Grandeur".

 * At the end of the game, the rear section of the ship Master Chief is on, the UNSC Forward Unto Dawn, drifts toward a planet as the Marathon logo flashes on the surface. Alex Seropian once stated that Master Chief and the main character of Marathon were the same character. Bungie has since denied this, with Seropian explaining that they weren't the same person, but different reincarnations of the same character.
 * A fictional company, Traxus Heavy Industries is introduced. Traxus IV was the name of a famous rampant AI in Marathon's universe. Additionally, in the level The Storm, Traxus IV can be seen etched on the glass panels in the warehouses.
 * The Brute Mauler was probably based on the shotgun from Marathon, which was also dual-wieldable.

Halo 3: ODST
The avatar used to represent the AI Tycho from Marathon was added to the list of emblems under the same name as the AI. It is also the second emblem to be added to Halo with affiliation to Marathon.

Marathon logo

 * The difficulty shields, yet again, have the Marathon logo imprinted on them. Halo 3: ODST is the last Halo game by Bungie to have the Marathon logo-imprinted difficulty shields.
 * At the very start of Uplift Reserve, the Marathon logo can be found.
 * In the HUD Menu the Marathon logo is behind the Triad logo.
 * Before entering the elevator in the campaign level Coastal Highway, if one jumps above the circular structure near the door, it makes the shape of the Marathon symbol.

The Babysitter
A symbol is seen on a rock when the whole waterfall is visible. As well as inside the waterfall at the base.

Halo: Reach
Bungie avoided the use of the Marathon symbol in Halo: Reach, presumably due to property rights issues with Microsoft. The symbol has been removed from the emblem gallery, the difficulty icon shields, the hull of the Pillar of Autumn and replaced with the Seventh Column on Captain Keyes' ID patch. The symbol in the eye of the Forge Monitor has also been changed.
 * At the end of the level Long Night of Solace, ATC 1 shouts, "They're everywhere!" This is an iconic line of the BOBs in the original Marathon.
 * On rare occasions, enemy NPCs known as "BOBs" may be encountered by the player. This name is a reference to the BOBs of the Marathon series, humans who were born onboard the titular colony ship.
 * A symbol that resembles the Marathon logo can be found on the seat of the Wraith's Plasma cannon turret.
 * While not appearing fully in the actual game itself, the whole symbol can still be seen in early concept art owned by Microsoft. In a scene depicting UNSC forces on the move, the golden decal is located on the right-most Spartan, on his/her upper left chest plate.

Halo: Glasslands
Some Sangheili believe that "Demons" are actually corpses reanimated through artificial means to continue fighting as supersoldiers. This is reminiscent of the battleroids from the Marathon trilogy. Likewise, battleroids are brought back from the dead to serve as physically and technologically augmented supersoldiers. The player character is a Mjolnir Mark IV battleroid.

Halo 4

 * The Reclaimer symbol has visually retconned, though it still clearly resembles the Marathon logo.
 * In the opening cinematic of the Spartan Ops episode Invasion, a Marine yells, "They're everywhere!"; this is a notorious line spoken by the BoBs in the original Marathon. However, Marathon is owned by Bungie, not 343 Industries, so it is probably coincidental.
 * The original Marathon symbol is seen on holographic panels in the final Spartan Ops chapter of Key.
