These are rough maps, not really meant to be played together, but separately just for fun. Note: Maze and Friendly Fire Central look similar because they were originally same map. FF is more carnage based.

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.

14 levels spread over three paths.

Rubicon X highly suggested.

Notes for version 2013:

Now with "more better"! (Still some suck included, as I haven't worked on it in almost a year. Pretty sure its as done as it will ever be.)

A one-level scenario where the player must seek out and punch the seven pumpkin beacons while avoiding Shades, Wraiths, and the occasional Pfhor.

Includes plugin that must be enabled for scenario to work properly.

Volume Warning: screamer.

Notes for version 1.02:

Embedded Increased Dynamic Limits back to Aleph One 1.0 amounts.

Fixed glow mask artifacts with fire sprites.

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.

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.

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!

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.

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!

Checkpoints is an implementation of Halo-style automatic saved games in the middle of a level. Mapmakers use annotations to mark where checkpoints should occur, and the Lua script does the rest. It also creates a save point after each level transition.

Includes a sample map. Find all seven checkpoints!
