A 35-level single player major conversion.

This scenario is difficult and action-packed; it features a full arsenal of new, powerful weapons, and more threatening enemies than you could ever want.

1.4 has new Lua features like a performance overlay, weapon buffs, a lot of little bug fixes; it also applies ammo capacity limits on Total Carnage. Requires Aleph One 1.5 or newer, probably!

Notes for version 1.4.2:

Adds graphics plugins by W'rkncacnter to improve weapons in hand and landscapes. On the linked webpage you can also find a download just for the plugins, which you should be able to drop into an existing 1.4.1 installation.

Mararthon: Yuge is a 30 level scenario, plus 225 secret levels for many extra hours of gameplay.

Yuge is a community project that was created in 2017 with procedural level generation using rooms that were mapped by hand. Mappers contributed rooms of various design and size, which were then fed into the level generator, which created the overall level layouts, texturing, monster placements, items, and sounds. Therefore, you will see some of the same rooms multiple times while playing through the scenario, but each will likely have a different set of monsters in slightly different locations, different textures, and you will likely have different weapons.

The level generator was created by W'rkncacnter, and 353 unique mapped out areas were contributed by several mappers: Windbreaker, RyokoTK, Sankara, W'rkncacnter, President People, $lave, General Tacticus, Glamdring, and Adminn_1.

Yuge has 2 new weapons, 2 new boss monsters, new wall textures, new scenery objects, maps with precipitation, and a new liquid type. Along with the procedurally generated levels, the final level of the main scenario, "enter the DOUCHE", is a custom map created by Windbreaker.

• Use of crystals to use special powers, along with conventional weapons.
• RPG elements.
• An ending score based on how you do while playing the game.

Make sure to read the readme for important information about controls. There are some non-obvious things you need to be aware of when playing the game. If you get stuck, there is a link to some Youtube videos in the readme that can be used as a guide.

Notes for version 1.4:

• Updated fog to work with the new version of Aleph One.

Marathon: Istoria is a single-player RPG scenario set in the Marathon universe and designed for the Aleph One engine. It pushes the engine to its limits by using advanced character progression, combat, and storytelling.

Customize your character by choosing from seven different player classes, each with their own unique active and passive abilities. Decide which conventional weapons you want to specialize in, and make use of a brand new arsenal of spells. Explore Istoria while discovering its secrets and how you fit in the world through a combination of terminals and communicating with the recently deceased. Istoria features an original soundtrack by Jon Irons.

Notes for version 1.1:

• Redesigned boss fight.
• New spells sounds to replace some of the weaker sounds from the previous version.
• New spherical mapped landscapes are available.
• Spells can now be accessed using a hotkey while holding down the aux trigger.
• MOAHs can fit in smaller spaces and are a new color.
• The game will automatically be saved upon completion, so you can easily reload to see your score.
• Uses class activations instead of body dialogue in score calculation.
• Black holes will no longer throw dead bodies around, which was especially dangerous for MOAHs. Terminals should display correctly in unusual aspect ratios.
• Various bug fixes and typo corrections.
• Overhead map filtering performance optimizations.
• Option to replace included soundtrack files with high-quality Bandcamp versions.
• Minor probability tweaks for "roaming" soundtrack event.
• Survival levels now let you choose Random for your class, and the game will choose for you.

This is a demo/proof of concept release for an OPEN-TO-EVERYONE COMMUNITY MAPPING PROJECT, Durandal Done Different. Inspired by community projects for Doom, such as Doom The Way Id Did, DDD is a celebration of the original game, its limitations, quirks and strengths.

The end goal of this project is to recreate, in the "style" of the original game, the entire 28-level campaign for Marathon 2. This isn't strictly speaking remakes of the original levels, but just a different interpretation of the writing and story beats as if it were 1995 all over again.

This 3-level demo features my replacements for Waterloo Waterpark, Slings and Arrows, and What About Bob. They're meant as a demonstration of the project's objective.

You are welcome to contribute! A direct link to the Discord for development of this project is in the text file of this download, or you can ask me for it on the main Marathon discord. Or you can just play the 3 maps included and wait patiently for the final release, sometime in the heavens...

Tempus Irae Redux is the classic Marathon Infinity scenario, remastered. This final release features enhanced HD graphics, with every single texture having been completely rebuilt from scratch. In addition, several new textures have been created (including animated textures), and the four original landscapes have now been expanded to thirteen. Each level has been meticulously refined and enhanced (and in some cases expanded), while introducing stunning effects like rain, lightning, fog, volcanic cinders, and snow. The game has also been upgraded with an all new soundtrack, and improved co-op play. If that wasn’t enough, new levels have been added as we’ve bridged Tempus Irae with the follow up project The Lost levels for a combined total of 49 solo levels, and 79 net maps.

This is the definitive and complete collection, every add-on united, at last.

We sincerely hope you’ll find this fresh take on Tempus Irae, led by the original scenario designers, to be worthy of a new playthrough as you discover its new secrets and challenges. It’s been over 25 years since the original release of the scenario, and this new version is absolutely breathtaking. From all of us at Nardo, have fun, and enjoy!

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 (a huge thanks to Solra Bizna for the menu system), 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. (A huge thanks to General-RADIX for these.)
• Fixes to dozens of physics inconsistencies. (A huge thanks to Irons for his help with this.)
• 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.

This is an English translation of the Aleph One scenario "Blauwe Vingers", originally in Dutch. All due credit for the original scenario and game content belongs to Tim Vogel and Stage Game Studio. The translation was the combined effort of myself, Drictelt, and Google's translation service.

This is a translation of the map file only, which means only terminal text, map text, level names, and console text are translated. Everything else, like interface text, loading screen text, and audio, is unchanged at this time.

To install, move Kaart.sceA into the "Data" subfolder of your Blauwe Vingers installation. For more information, see the included read me file.

Enjoy!

Notes for version 1.2 English:

This is the first release, compatible with Blauwe Vingers 1.2.

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.

A 25 level solo scenario, seven years in the making, Marathon: W'rkncacnter explores the player's future after the final level of Marathon Infinity.

Although it uses standard Marathon Infinity shapes, monsters, and weapons, Marathon W'rkncacnter features stunning architecture and use of the cutting edge persistent Lua feature of Aleph One.

Coming soon: the Marathon: W'rkncacnter net map pack.

WARNING: There are story spoilers in the reviews! Don't read them if you don't want to be spoiled.

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.

Special thanks to Hypersleep.

A two-level mini-scenario consisting of maps that were intended to become part of Marathon Syndicate, itself a project building on Marathon Rubicon.

Maps are by myself. Project Syndicate was by Cryos, Drictelt, effigy, Goran, Lhowon and John Doe; the maps rely on some textures and a terminal picture by others in the team.
