At long last, here is the continuation of my surrealist total conversion, "Spatial Outpouring", the first chapter of which was developed back in 2015-2016, and released in 2018.

I had the idea of creating a 'psychedelic' marathon scenario with a highly otherworldly plot, and heavy use of bright colors and fractals.

I also used synthesizers to create copious sound FX and ambiences for the game, and included an original song of mine in the title screen (this second chapter contains a different original song than was included with the first).

This second chapter was mostly developed years ago, but progress slowed to a halt for a long time, as I was frustrated trying to make the bizarre levels a playable experience.

Public appreciation for the 1st chapter has now led me to finish what I started, and here you have it - 3 new levels. I am pleased to say that at this point, this new material is truly the natural continuation to the original, and goes deeper into strangeness than ever before.

Notes for version 1.1:

Texture fix on level 2.

After all, what is a metastable AI but an electric god?

You've been sent by Durandal to assist a UESC assault on the Vylae homeworld. As Pfhor resistance crumbles, a strange discovery offers new opportunities... and new perils.

A mini-scenario for Marathon Infinity. Eight levels, plus one interstitial and one secret bonus level.

Notes for version 1.2:

Notable changes in v1.2:

• Added chapter screens
• Added bookend levels (Before Top Dead Center and All Farewells Are Sudden)
• Fixed issues with respawning Super Troopers and chip insertion on Atom Heart Mother
• Tweaked story throughout to give more context for player actions and set up Part 3 (Coming Soon!)
• Fixed miscellaneous bugs and typos throughout

Notes for version unburied.0:

Apparently this scenario had gone lost. This is what I found on my backup drive. I suspect it is the final version, but I'm not entirely sure.

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!

NOTE: Simplici7y will not let me upload anything to the old entry, so this is a reupload.

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

Install like any other plugin, the old versions had you manually replace the stock music but this is no longer required. Run like any other plugin.

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.

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.

Archive of the original Marathon Rubicon release for classic MacOS Aleph One, titled Rubicon AO Light. This is the Rubicon scenario as it was before Rubicon X.

The files on this archive were taken from the Macintosh Garden here https://macintoshgarden.org/games/marathon-rubicon and passed through MacBinary II+ to make them compatible with modern Aleph One for Windows and Linux too.

Also included is a set of maps bundled with the AO Light release, including some netmaps, the Rubicon Xariim scenario and, as far as I can tell, one ported map from the unreleased scenarios that eventually became Rubicon.

Notes for version 2:

Added the weapons and items MML scripts from Rubicon X to fix wrong names in the HUD.

This is the Marathon Victum Demo. Only the maps and shapes file are included. This is compatible with the hi-res shots, WEP pack and partially with the texture enhancement pack.

Because Victum uses Marathon 2's Water, Sewage, Lava, and Pfhor texture sets as well as the Marathon Infinity Jjaro set, it would not be logical to simply add the M2 or Marathon Infinity enhancement packs because they would make the game look wrong. What you need to do is get both the Infinity and Durandal enhancement packs, then use the Marathon infinity texture script and folders, but then copy over the four Marathon 2 sets in the marathon infinity texture folder, so the folder will be like so:

-Jjaro hi-res set -M2 water hi-res -M2 sewage hi-res -M2 pfhor hi-res -M2 lava hi-res -Marathon Infinity hi-res script

Backstory: Marathon Infinity was a dream of sorts, and Marathon 2 has just ended. You awake aboard a human-built ship.

It's sweet and simple because it will be explained in the first level.

Known bugs: The third level has no ambient or random sounds.

Marathon® Infinity takes the closed universe of the Marathon series and blows it wide open. The solo/co-op campaign, “Blood Tides of Lh’owon,” is a 20-level scenario sporting new textures, weapons, and aliens. More than that, the scenario sheds a surprising new light on the story’s characters and the meaning of events. Having defeated the Pfhor and reawakened the ancient remnants of the S’pht, the player now faces a world where friends become enemies and all is not what it seems…

Marathon Infinity is the most popular Marathon game in online play, and is compatible with hundreds of community-made maps. This release includes the classic graphics, and revamped high-definition textures and weapons.

This is 1 single player map. It was supposed to be part of a 3 map intro to an 11 map campaign that started a year ago. I'm hoping to get the next two maps added over the next month. Doubt I'll ever find the time to create the full campaign.

New physics file, new shapes file, and the merged map file are included in the download.

Physics of monsters has been modified so they act a little different.

The behavior of every gun has been modified. No assault rifle.

No new art.

If you're getting frustrated or just want to goof around, there's a secret door right at the start which leads to a Cheat Room containing all the guns and a recharger.

Notes for version 1.3.1:

-Added 3rd level

-Changed shotgun behavior

-Added terminal explaining new pistol behavior to 1st level, also added ammo

-Added sounds to 2nd level

-Included physics and shapes file, along with infinity's original music and sound files

-12/28/15: made a change so that you actually transport to level 3 after level 2

Welcome to The BOB Factory version 1.0.1 !

Those friendly little BOBs have been kidnapped by the Pfhor for experimental purposes! After being sacked by Durandal and friends a few hundred years ago, the Pfhor Empire has almost reached it's former glory, save for one small detail...what to do about Earth and all those superhuman space marines. So those wily aliens built The BOB Factory. There they plan to develop a new type of assimilated BOB, one that is indistinguishable from normal humans and doesn't say silly things to give itself away. If they reach Earth, those assimilateds would wreak total havoc. This is where you step in and save the day...Space Marine.

Notes for version 1.0.1:

The map consists of 3 levels

Version 1.0.1 fixes the terms & pattern buffers -- making the terms look like terms and the pattern buffers look like pattern buffers.

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.

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:

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.

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...
