These are compatibility files for Wheels! (a marathon engine game) to make it work in Aleph One. If you happen to own Wheels!, you can combine it with these files to play it with Aleph One. The original game supported input devices for people learning to use a wheel chair, and I don't know if those work in Aleph One. You will be limited by whatever inputs it supports, so this is mostly just for people curious to go through the game outside the context of its original purpose.

The Map file for Marathon 2: Durandal, as it was presented in the Windows 95 release.

The Windows map file contains several visual (and a few gameplay altering) changes from the Mac version, many small, some big. It also has a few altered terminal images.

Anyone familiar with "Waterloo Waterpark" will immediately be surprised with this rendition.

There are some players who do prefer the Windows map, so I decided it would be worth posting on Simplici7y.

The M2 Win95 map file is not particularly hard to obtain, as it is available in retail M2 copies for Windows, and it's available as a download on the Trilogy Release site, HOWEVER, that merge does not contain chapter screen sound effects. I re-merged the map file with the Mac version's sound resource folder, so now all chapter screens will play the appropriate sound.

"An enormous 6-level total conversion. (Well, okay, not total... and that's its biggest weakness.) The mapmaking is pretty good, and the new creatures are quite cool (you can see them in a series of very nice pics here if you're up for a 3 meg download, or get an idea from this 500K desktop picture), but I was bugged a bit when a new monster, with lots of new looks/sounds, died with an old sound, or fired with an old sound, or... Okay, it's a trivial complaint. Overall, this is really, really well done. It's been out for a while (as have lots of the recent uploads), but it's the first time I've seen it, and maybe you, too. Lots of art, lots of sound, lots of music (that's where all the new size comes from)."

It is 40 years after the combined forces of Earth and the S'pht Kr sacked the Pfhor system. You were put back into stasis after your legendary battles at Tau Ceti and L'howon. You've been recalled from stasis to help the UESC on a mission of utmost importance. You are aboard the UESC Leviathan and headed towards the Kolana system. Hobbes, the onboard AI, informs you of the situation. The Pfhor are back. So are the S'pht. More importantly, there is a new player in town, an AI called Wanda.

Features:

• An epic 3-way battle for the Jjaro AI with fluid alliances. Fight with the S'pht against the Pfhor, fight with the Pfhor against the S'pht. Fight alone against everyone.
• A new texture set
• 12 solo levels

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!

Update 3/3/25 - You can also find a Trojan standalone edition here https://hhas01.itch.io/trojan-se

"James’ Trojan AO scenario (2020) is a highly faithful warts-n-all port of the original M1 Trojan. This was important for historical preservation of early Marathon history, but not a great gameplay experience itself.

Trojan Standalone Edition (2021) made numerous fixes and enhancements to James’ scenario and customizations to the engine code. That’s why it’s released as Standalone Edition, not an add-on."

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

"What a hoot! If you enjoyed revisiting Earth in Tempus Irae, you're going to really like your "Vacation In Vilcabamba". The mapmaking is excellent and more than sufficiently puzzly, the new textures are gorgeous, the terminals are completely proof-read, the AI is moderately twisted, and the monster placement is quite good, with a new baddie for you to wrestle with. My only disappointment was that it was only one level; I finished it cheering for more." Description by Rigger

Created by Daniel Thomas

I have applied the old Mac patches and converted to files that modern Aleph One will read. Enjoy! -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 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 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.

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.

Weekly updates on Github: https://github.com/ravenshining/M1R

A project to give Marathon 1 a facelift, incorporating the new features of Aleph One to flesh out and add realism to the Marathon's architecture. Eventually, to include a branching storyline- possibly even missions on the colony moon.

Featuring Marathon 1 with lua scripting, liquids, ambient sound, new weapons, more scenery, improved sprites, expanded architecture, new terms & terminal art, and the latest HD plugins. Also including Craig Hardgrove's soundtrack, you can visit his page over at themarathonmusic.com !

At this point M1R should contain a complete, playable, almost bug-free recreation of M1, however, I still consider this an alpha as there are many more features and levels to come, and other features present that will be cut.

To contribute to this project, download it and read the "Help Wanted.txt" and/or TODO.txt," or head over to the Pfhorums where the lists and discussion are posted: http://pfhorums.com/viewtopic.php?f=13&t=53510

WINDOWS USERS PLEASE NOTE Marathon 1 Redux's extensive HD and 3D assets may cause 32-bit builds of Aleph One to crash immediately upon starting a game. To resolve this issue, you will have to experiment with turning off plugins or reducing texture replacement resolution to taste.

Notes for version 0.0.13-alpha:

• Starting a new game now brings you directly to Arrival, rather than skipping though unfinished prologues
• Currently unplayable levels are hidden from the level-select dialogue
• Lua scripting is finding its way to several levels to control special events and functions
• 3D models fixed so they no longer cause clipping & bloom problems, and distort less on pulsating textures
• New texture variants, bringing the total number to 386! (including landscapes and animation frames)
• Most levels updated to greater and lesser degrees to take advantage of the new textures
• AI variant terminal textures applied to every terminal - e.g., a Leela terminal says LEELA on it in-world
• Differentiated solid and liquid lava, and to a lesser degree, goo
• New epilogue level (thanks to Pfhorrest for letting me re-use some Eternal geometry)
• A new defensive twist to Pfhoraphobia to balance out its new Lua scripting
• Updates to Arrival, The Rose, Welcome to the Revolution, Try Again, Beware of Low-Flying Defence Drones
• The first Pfhor terminal
• Pfhor fighter sprites optimised for bloom
• Revised Vidmaster's Oath
• Newly spawned players start with plot-appropriate weapons, at the expense of ammo
• Low resolution fallback if you disable the 3072p landscape plugin
• Lots of bugfixes in general, thank you to everyone who reported problems!
• Much saner organisation overall
• Probably more because it's been 9 months since 0.0.12!

Known bugs A mutant pfhor teleports into space and BoBs clog corridors in the epilogue level, both fixed in weelky release Flamethrower is wonky *Player's light is too dark, fixed in weekly release

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.

Keep and eye out for a URL within the secret levels where you can download even more bonus maps.

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.

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.
