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.

NOTE: the "microphone" key in Aleph One has recently been changed to the "aux trigger" key, which is important to know for Istoria.

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

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.

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

In this new NEFX scenario shell for Marathon Aleph One, travel around a corn maze to get to the exit without a map. If you try to use a map, you'll die, because that's cheating. So really use your navigational skills, prowess, memory, etc. You'll become a better person if you persevere through this.

Notes for version 2023-10-29:

Today I added one new map for Marathon: Corn Maze, "The Weight of Cumulative Collective Memory". This can be downloaded individually or with the scenario itself at the provided link.

In this latest NEFX shell to be added to map-wise over time, you accidentally teleport into a messy, long-abandoned, and now-infested storage complex run by an AI who has gotten imaginative in isolation but who is thwarted in progress and needs someone to retrieve missing keys amidst a great mess in order to both grow unabated and help you escape. All maps in this scenario shall be Retrieval missions.

Notes for version 2023-08-16:

I added a new map, "NEFX - Dawned Age First Sight and Strike". You can download it and other maps either individually or together at the provided link.

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!

This is a 30 level scenario that truly deserves official sequel status to the original Marathon trilogy. We're so confident about that, that we're calling it Marathon 4. There are too many people that helped with this project that it's impossible to name everyone. Thank you all fans of marathon!

This scenario is truly groundbreaking in that every time you play the game, your experience will be different. No two players will ever have the same experience playing through this game. The replayability is endless!

"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

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

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.
