Notes for version v1.2:

from the readme:

Users must have Aleph One 0.16 or higher. "Marathon Dissent.bin" in the read me folder can be decoded (.bin file) and used with the the decoded (.bin) Image and Map files in classic. The look and feel of the game should be the same. The mml scripts are for text strings and opengl code.

Portal of Sigma is an Aleph One scenario with a new story, landscapes, textures, weapons, and updated sprites.

I've repackaged it and fixed a few things with the MML to make everything work with modern Aleph One. -Shappie

Phoenix Falling is a large M1 scenario of 44 levels featuring a new story with new characters, weapons, creatures, sounds, shapes, and more. (48 with secret levels and one network level)

Please keep in mind - there are bugs in this release. Most of these are caused by running the game in the Aleph One engine, which did not yet exist when the scenario was created. This used to be run with the original M1 engine.

Some of the largest known bugs are related to shapes not rendering correctly with chairs, tracer rounds from the brass gun, the weapon display in the HUD interface, and most of the new creature animations.

Repackaged for Simplici7y with permission from the Phoenix Falling creators, Matt & Andrew Schenk.

Notes for version 1.3:

This version has a fixed Map file that should allow terminals to function in the vacuum levels.

A 22 level single player game with brand new terminal art, weapons, environments, characters, and a story fleshing out the Marathon universe.

This scenario had become unattainable save for a single place, the Marathon Total Carnage Pack. I extracted and repackaged it to upload here, so everyone can access and enjoy this incredible scenario.

It is technically "unfinished" but only in the sense that it is missing some polish. It is essentially complete and you can play through the entire scenario without issue. Read the read me file for more information about Apotheosis.

Eupfhoria - Marathon Soundtrack Remake

Eupfhoria is a fully re-instrumented and re-scored soundtrack mod for the first Marathon. This replacement tries to remaster the original soundtrack while retaining the original feel. It IS the tracks you know and love, as it's based off the original MIDI files. Most tracks should fuller and more atmospheric, hopefully a bit like Marathon's younger brother, Halo.

To see if this is for you without downloading, you can stream it all here: Eupfhoria - Full Album Stream

Installation is simple, just replace your Music folder found in the Marathon directory. Backup your original folder if you want to go back to the originals.

NOTE: Don't use this for your first playthrough. Really. This is for people who've played through it before and want a new experience. Updating those pesky textures is one thing, but save this for your second playthrough.

Notes for version 1.1:

Updated files to work with all versions of AlephOne. Simply replace the files in your Music folder of Marathon 1 with the files in this link.

In this new NEFX scenario shell for Marathon Aleph One, travel around a corn maze to get to the exit without a map. If you try to use a map, you'll die, because that's cheating. So really use your navigational skills, prowess, memory, etc. You'll become a better person if you persevere through this.

Notes for version 2023-10-29:

Today I added one new map for Marathon: Corn Maze, "The Weight of Cumulative Collective Memory". This can be downloaded individually or with the scenario itself at the provided link.

Eternal is one of the largest scenarios ever created for Aleph One, initially created by Forrest Cameranesi (Pfhorrest) and subsequently revised and expanded by a massive team known as the Xeventh Project, which, as of this update (March 2024) now includes more than 40 people. Besides Tempus Irae, it may be the oldest scenario still being actively developed; it was first released in 2004 and has been refined and expanded almost continuously ever since. Features include, but are hardly limited to:

• 52 levels, some revisiting familiar locations from the Marathon trilogy and some being among the largest ever created for the engine
• An intricately layered plot featuring dense political and philosophical themes, a tragic romance, time travel, major events from the Marathon trilogy’s backstory, complex original characters, and returning faces from the trilogy’s cast
• A huge, acclaimed soundtrack with unique music for every level, lasting more than seven hours total, and created by over a dozen composers and arrangers (significantly expanded in 1.3 previews 4 through 6)
• Redesigns of most of the game’s familiar cast (new in 1.3), some old foes from Pathways into Darkness, and some new faces (some new in 1.3)
• Hundreds of gorgeous terminal images (many added for 1.3 preview 4 through 6)
• Five texture sets, encompassing 650 high-resolution textures, 12 detailed original landscape textures, and several separate human and alien environments
• An in-game menu system (new in 1.3 preview 6) that toggles several optional features, including:
  • Simplified overhead map views in around twenty levels (new in 1.3 preview 6)
  • A secret tracking system (new in 1.3 preview 4)
  • Auto-save the game on level transition (new in 1.3)
  • An RPG-style monster health display (new in 1.3 preview 6)
  • Shared pickups between players in network games (new in 1.3 preview 6)
  • Disabled friendly fire between players in network games (new in 1.3 preview 6)
• More than 360 sounds, remixed or remastered in CD quality, in stereo where possible (new in 1.3)
• Atmospheric weather like rain and snow (new in 1.3)
• A final boss battle of sorts (new in 1.3)
• Detailed documentation including illustrated field guides to Eternal’s weaponry, aliens, and humans, detailed credits, a meta-history of Eternal, and technical notes on how its maps and scripts work (new in 1.3)

The current development release, 1.3 preview 6 (released on 2024-03-07), is perfectly playable despite still being incomplete; it is now our recommended way to play the game. We’ll refrain from estimating the release date of 1.3 final, as we’ve overshot too many estimates to count (thank you, feature creep). The current “stable” build, 1.2.1 (released on 2021-11-07), is missing several features listed above but is still an enjoyable game in its own right.

The screenshots seen on the right are from a development release from between 1.3 previews 4 and 5 and are a reasonable reflection of Eternal’s current appearance. Although they were taken on Normal (so as to show more monster types), we do recommend playing Eternal on the highest difficulty you can manage.

Notes for version 1.3 preview 6:

Current development release. 1.3 incorporates several new features, many detailed above. New in 1.3 preview 6:

• Hard requirement of Aleph One 1.7 or later.
• An in-game menu system that toggles a ton of new optional scripts, including:
  • Hide irrelevant layers of the overhead map (a massive aid to navigation).
  • RPG-style monster health display.
  • Disable friendly fire in cooperative games.
  • Shared item pickups in cooperative games.
• New drone and Juggernaut sprites in chapter four.
• Fixes to dozens of physics inconsistencies.
• Major music changes:
  • Every level now has at least one unique music track.
  • “We Met Once in the Garden” now uses multiple tracks that shift depending on in-game events, à la FTL or Cadence of Hyrule – to our knowledge, this is the first scenario to make use of Aleph One 1.7’s dynamic music features, though in a relatively simple fashion.
  • Seventeen of Craig Hardgrove’s tracks have been newly remastered or remixed from newly available, much higher-quality sources, some multiple times.
  • The game soundtrack is now encoded as Opus, the objectively best lossy music codec by every performance metric.
  • True obsessives may use an optional lossless FLAC version for the in-game soundtrack.
• New (or newly accessible) areas in “Deja Vu All Over Again”, “Roots and Radicals”, “Core Done Blew”, “A Friend in Need”, “Frog Blast the Vent Core”, and “I’ve Got a Bad Feeling About This”.

Additions to preview 5:

• Fixes to several major bugs, including crashes in six different levels, the HUD messing up in non-16:9 aspect ratios, and problems in network games with the secret counter and map overlay.
• Over an hour of new/updated music since preview 4.
• New secrets in a few levels.
• Jjaro sludge is no longer coloured like M1’s toxic Pfhor goo.

Kill Them All is a short but intense mini-scenario for Marathon Infinity. It is a collaborative project, wherein the goal for each mapper was to make complete, high-quality maps that had no more than 100 polygons.

KTA features 15 levels by myself, screamingfool, Kinetic Turtle, irons, and Shadowbreaker. It's a difficult but action-packed game -- very fun.

9 levels. This may be the most difficult scenario you will ever play.

Here's a review from the only person I know that completed it.

I just finished Ra'thor (except for the hidden level, which I did not find the entry point for).

"I've been playing Marathon since late '95, and think I'm a pretty good player, but your scenario is hands down the most difficult I've ever played. In fact, I'd say it's pretty near impossible to beat on Total Carnage, especially the last 3 vacuum levels. I freely admit that I cheated constantly for oxygen and once or twice for ammo (especially on Igor Ra'thor), and occasionally used Forge. I do have a life, and I just didn't have the time (or desire) to play those levels over and over again to reach the level of perfection needed to complete them on the available oxygen or ammo (at least what I could find). I believe I never cheated for shields, but I may be mistaken. It took me a long time to get through the maps, so memory fades. You made free use of hidden switches that made things that much harder".

Notes for version I:

This scenario was created back in 1998 and is based on Marathon EVIL. It's my original version and is meant to be almost impossible to complete. I'm working on an updated version that will be much easier and include 2 new levels...Version II coming soon!

In this new scenario shell from NEFX, solve platform puzzles to reach the Shells of Ascension and escape.

Notes for version 2024-04-18:

The scenario shell is completed, with one level so far. I intend to release more levels in the future to be played in any order wished.

Apotheosis X is a total conversion featuring 24 massive levels of carnage brought to life with entirely reimagined sprites and textures, high frame rate animations, 16 bit audio and an original soundtrack.

The campaign features engaging combat that scales with player skill and aggression, with a roster of new enemies and weaponry that complements the original games' nuance and high skill ceiling.

Notes for version 1.1:

Key updates for 1.1:

• Sound effects are louder and punchier, with more variety.
• The player's arsenal is more powerful, with many adjustments that make it more effective on total carnage.
• Additional saves, items and resources throughout the campaign.
• Weapon and item pickups are more visible.
• Numerous bug fixes, including the removal of 2 soft locks.
• Numerous small updates to level designs.
• Included PDF manual with a weapon manifest and additional backstory.

An extensive list of updates is available in the download.

My first ever finished game, a final project during my art studies at VMA in 2008/2009.

An experiment in how far one can go by stripping the elements of a video game down to its bare essentials of mechanics, dynamics and aesthetics, while in the meantime, showcasing the importance and the purpose of audial elements in interactive entertainment.

Set in a bleak sterile world of white, where nothing exists except the disturbingly pure visuals, the game follows the avatar's journey through the bleak levels of the world, accompanied by a soundtrack, to migrate and merge to the unknown entity which called for him.

Susannah was showcased at the Þrír í Þriðja exhibition in Verksmiðjan, Hjalteyri (Iceland) in 2009.

Play as a replicant designed by Lysander.

Project Iris is a Rubicon scenario which will likely never be finished.

It features two full-fledged levels and a transition level.

Violet is arguably the best map I've ever made and I am happy to share it for others to enjoy. The level is meant to take place halfway through the story, so expect in medias res-style terminals.

Additional notes:

• Your unarmed secondary is a "kick" with major knockback.

• You will need Rubicon X to play this scenario. Make sure to follow the instructions I've included in the zip.

Notes for version 1.1:

• Hotfix: Door in Dry Petals On My Espresso Martini was locked by default

KTA3: The Complete Masterworks is every Kill Them All map to date, as well as 12 new maps, in one massive 38-map mega-mini-scenario adventure.

If you want to play co-op, using Co-op.lua is nearly a requirement.

Notes for version 1.10:

Added two more maps and fixed a lot of bugs, mostly related to co-op.

In this Aleph One Marathon scenario shell by NEFX, survive as long as you can and rack up as much time and score as you can fighting against intensifying waves of Pathways Into Darkness enemies with Pathways Into Darkness weapons. Like with Marathon: Machina, every level is open-ended, and there is nothing particularly won or lost except your competition with yourself and anyone else who dares to take on the Underrealm challenge and share their exploits. Good luck, endless fighter! There may well be more levels to come to be experienced in any order desired.

This fixes the issues from the original 2019 upload, meaning it doesn't have anyone else's plugin or any version of Aleph One in it. This was a joke made in response to Meerjel01's proposed scenario Marathon: Green. It's an extermination level, so return to the starting platform after killing everything. In the meantime, deal with all the green.

Notes for version 2:

Doesn't have anyone else's plugin or any earlier version of Aleph One in it. I used a custom texture to create the green this time, and it's easier and better to navigate this way anyway.
