Notes for version 1.01:

Fixed file loading on Linux and Mac OS. Changed "\" to "/" in mml folder paths.

A scenario set between Marathon 2 and Marathon Infinity. Intended to enhance the story experience of playing Infinity by giving enough context to work out key plot points as they happen in game.

As Departure intended as a prequel to Infinity it's fairly short. Only 12 levels and some of them are fairly short.

Any feedback is welcome. Alternatively feel free to unpack the game file with Atque and make improvements.

Notes for version 1.1:

Version 1.1 - Fixed bug in smaller walkway area of Noctem where player could clip through wall and be trapped in centre

NEFX loves you.

NEFX has been prolifically producing great Marathon/Aleph One inventions since 2017 (around 2.5 years after being founded) and uploading them to Simplici7y, in an increasing number of different upload pages that NEFX then frequently updates. This has occasionally lead to crowding of Simplici7y's front page with several different NEFX uploads, sometimes over a relatively short period. Understandably, some have objected to this as unfairly outcrowding and burying the wonderful contributions of our fellow travelers. We hear them. Therefore, to better serve the community as well as our Total Carnage Comrades, NEFX is now consolidating all additions and updates to its Marathon and Aleph One-related inventions on Simplici7y here on this one upload page, with a datemarked update timeline you can view below. Henceforth, all Marathon/Aleph One scenarios, campaigns, maps, mods, etc, and any updates to them, will be posted here. Of course, the webpage link connects to NEFX's Internet Archive homepage, where you can find all inventions by titled category. This includes:

NEFX Marathon Mods (i.e. physics files and Lua scripts for netplay)

NEFX Marathon Infinity Netmaps

NEFX Marathon Solomaps for others' scenarios, including the soundtracked 50-level pack for Aleph One: Wheels!

This is just the raw MML from M2 Pepperscapes by W'rkncacnter (not the uploader of this), without any of its actual landscapes. What it does is stretch landscapes across the entire screen, thus preventing any repetition/cut-off points. It looks a little goofy, but for high-FOV users, it may be preferable to the standard, small landscape size. It will work with Marathon 2, Infinity, and regular scenario landscapes (e.g. Phoenix's original landscapes). It will NOT affect modern HD landscapes, such as Phoenix's built-in HD landscapes plugin or Rubicon X's.

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.

A full scenario for Marathon Infinity. It is a 6 level breach and infiltrate mission into a Pfhor military compound, complete with new terminal and chapter arts, as well as some interesting old school mapping tricks and fun bits.

This version of the scenario was updated to Marathon Infinity (textures and refinements). If you want to play this scenario in Marathon 2, it is highly recommended you grab the other archive (specifically for M2), or many textures just won't look right on things.

Notes for version v2.0:

Final version for Siege of Nor'Korh.

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.

Notes for version 1.1:

• Redesigned boss fight.
• New spells sounds to replace some of the weaker sounds from the previous version.
• New spherical mapped landscapes are available.
• Spells can now be accessed using a hotkey while holding down the aux trigger.
• MOAHs can fit in smaller spaces and are a new color.
• The game will automatically be saved upon completion, so you can easily reload to see your score.
• Uses class activations instead of body dialogue in score calculation.
• Black holes will no longer throw dead bodies around, which was especially dangerous for MOAHs. Terminals should display correctly in unusual aspect ratios.
• Various bug fixes and typo corrections.
• Overhead map filtering performance optimizations.
• Option to replace included soundtrack files with high-quality Bandcamp versions.
• Minor probability tweaks for "roaming" soundtrack event.
• Survival levels now let you choose Random for your class, and the game will choose for you.

This is a map I made in college, ages ago. Heavily inspired by certain moments from the Rubicon solo campaign, but with its own unique twists.

This level is designed to be severely punishing, but absolutely doable with a sound strategy. There are ambushes. There are turret puzzles. There are times you'll have to run for your life.

One word of advice - you're not meant to fight every juggernaut. You can still try if you want to :)

Notes for version 1.0:

An original fan soundtrack for Marathon Infinity, composed by Talashar. Featuring themes from Marathon, Halo, and M2SE. This won't just be a mashup of themes you know though, levels and character have been given their own themes to provide a new dimension to the game. Experience Infinity in a whole new way. Based on Treellama's M2SE plugin.

Preview my music here: https://talashar.bandcamp.com/album/strange-aeons

NOTE: MUSIC DOES NOT LOOP ENDLESSLY. This is intended. Many levels have added silence to allow the ambience some time on the stage. This silence is not a bug. Each level has been assigned specific tracks to emphasize narrative beats, emotional highlights, atmosphere, and overall vibe. If you would like looping versions of the songs, you can get them for free via the bandcamp link (click Buy Album then enter $0).

Recommended volume levels are 100% Master, 70% Music.

If you run into any issues with this plugin, I can be found in the Marathon Discord as @throkgaar.

Enjoy.
