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

• Fixed miscellaneous bugs and typos throughout

NOTE: Many changes have gone into this game to address the two reviews. With over 900 downloads, I'd appreciate a review from someone else. Please? Many many updates to add pillars, stairs, transparency, different goals, etc. When this was originally reviewed, there were only 4 levels! Please review if you downloaded it.

=========

Fart or Die! is a 9-level game that uses hidden areas, terminals, switches, teleports, and more!

As a beginner, I struggled to figure out how to create switches, terminals, platforms, stairs, circles (use circle plugin around a line), uplink chips, exits and terminal variants with multiple actions. I also could not figure out how to add motion or depth to water, lava, or sewage. All that works now and is included in this game.

I am not an expert map maker by any means (more a newb) but this map contains a lot of commonly used elements for map makers and may help some newbs.

NOTE: I am not a super mapping pro and my levels are much less complex than others on here…but it is that complexity that made it hard for me to learn by studying other maps. I hope this set of maps helps someone new on here. This is NOT an advanced mapping tutorial. It is meant to help you get over the hump.

Having said all that, it is also fun to play and I enjoyed making it. While the levels are not too complex, they are challenging and require you to follow game strategy to move from one level to another. :) If you play the game at the hardest level, you will find it difficult to complete. :)

Let me know if you like it. I'm in the pfhorums as dustu and on live games as dustu.

NOTE: I have addressed most, if not all, of the comments by reviewers on here and in the forums.

If you download this, please review it.

Enjoy!

UPLOAD INTRODUCTION AND UPDATE TIMELINE BELOW

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 an old scenario from long ago, here for your convenience. Made with bits from the orphanage and a dormant map from adam ahswell's hard drive. All you need is a clean copy of the marathon basics, no custom pieces.

Notes for version 1.1:

updated the terminals to be spelled correctly.

3,373 downloads, 1 review, 1 screenshot, 4.0 rating

An incomplete scenario that was the prequel to Marathon: Dave (mainly known as Dave demo).

Please read the text document that comes with.

Notes for version 1.0:

1.0 - First time being released to the public besides the other versions for TBCROnline.

This requires the shapes and sounds from MPiD beta. I put them in the download so you'll already have them on hand if you didn't already have them.

fixed a couple of minor bugs and added ammo

A short solo map which was originally meant to be for KTA IV, but got a bit too big for the requirement, so instead of going to waste I finished it.

This will be the first time where I've used all the tools required to make a map with Aleph One.

Notes for version 1.0:

1.0 - Initial release

3,344 downloads, 3 reviews, 2 screenshots, 3.3 rating

Henseler´s Hell a map by RealRainman

Henseler´s Hell is the first and only "Marathon map" I made back in 1997. I tried to develop a detailed storyline that, although based on the familiar "I guide you through the action" concept, comes up with surprising twists and a couple of neat tricks that pushes even the experienced player to his limits. I wanted to include a lot of cool graphics (watch out for the terminals !) , and the biggest battlebot that the "Marathon" world has ever seen (I guess) !

Believe me, I used ALL the polygons,objects and entities that are possible to use in "Forge".

Notes for version 02:

Sorry guys, forgot about the fact that I uploaded here! A nice guy by the name of Greg (somehow) got in contact with me and pointed out the missing terminal pics! The HENSELER´S HELL map-file must have been corrupted years ago by copying it to a PC-file server. I was able to retrieve the original map file and it has all the terminal artwork included (which is important at some point in the story, visual hints etc.). Have fun! cheers, RealRainman

Perry Arena is my first map released to the public. It's packed full of carnage and uses the sewage texture set. M2 compatible. There are aliens and bobs for solo fun.

Notes for version 1.0.2:

Changed some sounds and monster parameters to improve flow.

Heretical Cyborg is VikingBoyBilly's first complete single player map. It is also customized for co-operative play. It is modeled after the first map of Heretic, E1M1 "The Docks," and is an attempt at remaking a Doom-engine map into the Marathon Infinity Engine.

It started off as an entry for Kill Them All: Volume IV, but the polygon count went up too high. Instead of letting it go to waste, here is this completed standalone map for you to play.

Notes for version 1.2:

Following a lot of suggestions from Ryoko and Brilliant, the shading has been enhanced, textures have been re-aligned, the architecture of the dock has been remade (the posts were missing before), and scenery has been added, with l'howon cylinders as a 'barrel' substitute.

I created these maps between 2000 - 2003. They have been uploaded before in a similar format. This pack adds one large solo map. I'm not sure about all this new fangled stuff you got here so you might need to tweak them a bit to work.

Notes for version 2:

Not sure what happened to the original; if it's still floating around somewhere. This is the new version.

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 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.
