This is the public beta of an ongoing solo scenario project. So far, seventeen levels have been made, containing twelve full solo levels and a net map. Enjoy.

Contained are all the scenario files, along with music. Included is the Total Weapon Enhancement Pack as standard, with altered alien weapon DDSs. Latest Aleph One is required. Operates stand-alone.

Please can you review it? This is a beta after all, and it'll be greatly appreciated for future reference. ß)

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.

"A 19-level solo masterpiece, with new sounds, shapes, terms, physics, bobs... and it's totally non-linear (you decide what order to do the levels in). Brought to you by the folks who did U.S.S. Raider, Athens Outpost, and the Marathon's Story page."

This scenario has been converted to an Aleph One compatible format and repackaged for Simplici7y.

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.

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.

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. Six levels, plus one interstitial and one secret bonus level.

Notes for version 1.1:

Notable changes in v1.1:

• Rebalanced ammo and shield chargers throughout scenario to provide a smoother difficulty curve and encourage exploration/aggression.
• Embedded MML+Lua (no longer requires Previous AI plugin)
• Substantially revised Atom Heart Mother (more climactic battles in central portion) and Our Lord Debussy (more to explore in upper floors, more connections between different areas of level).
• Removed potential Cask-of-Amontillado-esque soft lock in Sic Transit Gloria Mundi.
• Added a secret bonus level! Getting there is half the challenge.
• More weapon pickups on more levels, for those that prefer pistol starts (or just missed the weapon the first time around).
• Tweaks and aesthetic improvements to all levels.

I'm always looking to hone my craft as a mapper -- reviews, suggestions, &c are greatly appreciated. Special thanks to hypersleep for feedback on v1.0 and help with Lua!

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.

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.

Hosted on Mega because the Simplici7y uploader is failing to upload.

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.

Here it is, at last: Marathon TROJAN. Now compatible with Aleph One (1.3 or newer), this uses the native M1 files to deliver the original, unaltered experience we know from the 90's.

M1 compatible fullscreen HUD plugins will work with TROJAN if you don't want to use the included Classic HUD plugin.

Additional files include the Weapons Pump Patch, FAQ, Manual, Spoiler Guide, and read me's from older versions of TROJAN.

Special thank you to Hamish Sanderson for giving us permission to distribute this re-release of TROJAN. Enjoy!

Decided to release Glow as an unfinished game because it feels like it will change when The Silence gets released.

Glow is built from Lost Land's resources, which is why the menu image is the base game's as well as textures and sprites. Music is taken from my iTunes list which features Tineidae, Totakeke and Cybernetika. Don't use the songs for your scenario if you haven't brought them yourself. (Cybernetika's was however free) No copyright intended for any song. Removal is acceptable.

Don't criticize this scenario. It's unfinished and are only mean't as a glance of history.

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.

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".

D. Supanich, North Hollywood, CA (March 2003)

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!
