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.

Lost Lands is a 25 level conversion I created entirely myself.
I started working on it when I was roughly 12 years old and I now consider it finished and in reasonably playable shape now that I am 25, 13 years later. As you progress through the game, you can see my mapmaking grow gradually more complex, and the way I grew pre-occupied with experimental and surreal mapbuilding techniques.

The official soundtrack is available here -

Notes for version 1.11:

This version is an overhaul of the shapes file, replacing many embarrassing pixelated textures with more thematic, color coded and polished looking artwork.

I've also included the "Previous AI" plugin with the install to avoid issues with monsters failing to activate.

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 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

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.

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.

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...

In this entire 50-level scenario from NEFX, complete with an entire original soundtrack, you navigate strange, puzzling, and sometimes perilous terrain to clean up hard dust balls with your trusty Yucatan Suckaman™ vacuum cleaner. Just watch where you step, and be sure to empty the bag often so the vacuum cleaner doesn't explode!

Notes for version 2024-09-27:

Marathon: Sucks is now officially a full-fledged scenario. All 50 levels have been merged and flowed together into a pack complete with original music tracks and terminal messages. Get ready for some hardcore cleaning. You can download the whole package at the provided link as well as any of the individual maps.

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.

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.

M1A1 was a port of Marathon to Aleph One released in 2001 and updated in 2002 before Aleph One was able to use the original Marathon data files.

Today, Aleph One is able to play the original Marathon 1 which can be found at lhowon.org. Downloads for M1A1 will not work with Marathon 1. See the Marathon 1 scenario page for compatible files.

An archive of the the original M1A1 Project homepage can be found here.. Downloads can be found on the Fileball Archive.
