This is a concept map. Includes aliens for solo, and a ball, and a hill.

I made this map the day before our Carn Fest VI, so we could crash test it. We found a few things that needed fixing, and I fixed em on the fly. We then all came to a concesus that it was great, so we made a film and I would post it for others. Here it is, and a film included on how it's played.

There is one thing I might mention though... the physics have been altered, so that you can wield two NUKEGUNS at once. How it works is, you must first pickup one nukegun, and then pickup TWO ammo packs in order to use two nukegun. This is the only way it was possible of being done, so live with it. Shot damage has been GREATLY reduced so you need to hit them more than just once at a very far distance... made it more fair, after play testing it.

Known bugs that will not be fixed or listened too in eMail: Have to pickup ammo before using the weapon. Have to pick up more ammo in order to use a second. Only have to pick up one physical nukegun to use two. Player graphics from anothers point of view shows them holding dual pistols instead of dual nukeguns (this one is imposible to fix unless I made a stinking shapes patcher and got rid of pistols alltogether).

Just throw this map file into the folder of EVIL (or some folder within the Evil folder), and pick it from the Environment Preferences area. It has pre-merged Physics that are EVIL compatible, so no worry there.

Actually... ANY map made for use with EVIL should be pre-merged with physics, regardless. Otherwise it's not a map worth messing with.

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!

EMR 3.0 is a unique scenario based upon the Aleph One (Marathon) engine. As a Federation Marine resting after your last mission, you start aboard the exploration class Starship Kronos where you are re-acquainted with the AI Merlin, who introduces you to Kronos time traveling technology, and reveals your new mission: to save mankind from the clutches of Morgana and her minions.

Through untamed raptor-infested jungles, castle arenas, and war-torn streets of the future, you will wield weapons from all time periods - including the Sword of Power, Excalibur - in an effort to thwart the diabolical plot that unfolds. The EMR adventure, spread across 42 solo levels, weaves a tale of truth and honor, knighthood and bravery, and darkness and treachery. EMR also delivers 27 adrenaline pumped network levels. EMR immerses you in an amazing new world, creating an addictive, fun and unique gaming experience.

Notes for version 3.0:

This version incorporates the LUA plugin patch by pfhore into a complete download ZIP, playable "as is" with the most recent version of Aleph One (2025-03-02 release at time of writing).

You are a doll

An undead with the heart of a human made to serve. You are tasked with fighting to serve the Life Vessel, a massive vehicle carrying what remains of humanity. The world is dead, ruled by the undead and gods made by humanity's own hand.

You are strong

Your mutated body gives you enough strength to crush lesser foes in a single blow, but even that strength alone will not be enough. Throw your pistol, fire an impractical amount of shotguns, or charge up divine lighting.

You are clueless

With only scraps of memory of your past and little knowledge of the present, the future is a worrying prospect. You have little choice but to fight and hope some sense will emerge from your trials.

This 7 map scenario is only the first chapter of a black and white story.

It is recommended to play the alpha demo first as it functions as a prologue, though it is not required. You can find the demo here https://simplici7y.com/items/divine-twilight-alpha-demo/

Hint for those unfamiliar with Marathon: Switches can be hit from a distance with grenades or a thrown pistol.

Notes for version 1.0:

The first release of Chapter 1, Kiwi hopes you will enjoy it.

A single level map that acts as both a demo and prologue for Divine Twilight, a black and white scenario with an original story separate from Marathon.

Notes for version 1.01:

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

2,552 downloads, 0 reviews, 4 screenshots

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 2.1:

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

Version 2.0 - Fixed sticky polygons at start of Eye of Khfiva - Modified section with water level switch on Mallum Sommium, including adding a new path. - Various texture changes, ceiling modifications, and lighting tweaks, especially on Thirteen Bonfires and the larger areas of Elevate Injured Areas, Eye of Khfiva, and Endure. - Minor edits to some terminal text.

Version 2.1 - Fixed wrong start location in Mallum Sommium and polygon height to reenable Flick'ta beach assault (sorry about stuffing them up)

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.
