Play the Survival solo gameplay mode from Durandal XBLA. Rack up carnage points as you face off against hordes of increasingly difficult enemies.

Play on the four Survival maps built by Freeverse for the port. Or use the plugin, pick any netmap, and try not to die.

For a similar co-op experience, see Survival.lua.

Notes for version 2.1:

Version 2.1 fixes a bug which caused films to go out-of-sync.

This plugin increases the number of AI monsters active at any one time. The increased number was the default setting in Aleph One until 1.1, when the Marathon 2/Infinity defaults were restored.

You should use this plugin with scenarios built specifically for Aleph One, such as Eternal X, Kill Them All, or Phoenix. When/if those scenarios are updated, you will no longer need this plugin. Do not enable the plugin for scenarios orginally designed for Marathon Infinity, such as Tempus Irae.

A zip file version of the old 3D Examples from the early days of Aleph One. Includes a plugin containing 3D models of columns and lights, and two maps for trying it out. Files originally created by "binhqx", and still available in .sit form here

An evil hack of the Basic M1 HUD (as included with most A1 releases), but it has transparency, and is decorated slightly, so it's awesome.

Does Basic HUD's opaqueness get in your way? Do you like Enhanced HUD, but just can't get past the lack of the inventory panel? Then this might just be for you! Comes with tiny little weapons displays that just seem to morph into other shapes inexplicably. The UESC is crazy!

No refunds.

Get it for Marathon 2/Marathon Infinity!

Alternatively, get it on the Workshop!

Notes for version 1.2-alpha2:

• Brought to parity with the Marathon 2/Infinity versions code-wise kind of sort of.
• The rocket launcher rockets aren't as bunched up to the weapon itself anymore.

Notes for version 2.1.1:

This plugin contains the XBLA-style HUD distributed in the Marathon all-in-one download of Aleph One 1.0. It will not work with the native Marathon 1 downloads bundled with Aleph One 1.1 and later. A compatible version may be found in those downloads.

Notes for version 20120514:

This version fixes the display of extremely long player names.

One of the cooler features M1A1 took advantage of was animated textures. This plugin brings them back full circle to classic M1.

I made a few touch-ups, ranging from recoloring for accuracy to M1's palette, to smoothing out flickering pixels, to fixing some inconsistencies from the original game.

NOTES:

• I included the originals to any textures I made changes to, in case you prefer them or just want to see what I changed.

• The Durandal image on the puzzle switches is not used because (to my knowledge) it didn't appear in-game.

CREDITS:

• Original Textures - Bungie Software

UPLOAD INTRODUCTION AND UPDATE TIMELINE BELOW

000000000000000000000

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 a slightly modified version of the Default HUD created by Hopper: https://simplici7y.com/items/m2-default-hud/

This is meant for people that want the HUD to be small, but not obscure parts of the game world. If you are bothered by the black bar this usually leaves, it can be filled in with artwork. I've included several options for artwork in the resources/extra_images folder. Or you can create your own.

To size the HUD, you can use the typical HUD sizes in the options. However, they will all be smaller than the default HUD, as one of the goals of this plugin is to maximize the game world view.

The normal HUD also typically leaves black bars on the sides depending on your resolution and settings, and this HUD attempts to eliminate that from happening.

Notes for version 1.0:

If you downloaded a PepperHUD that was floating around from a long time ago, you should get this new version.

by Gregory Ewing greg.ewing@canterbury.ac.nz

This is a set of Ruby plug-in scripts for Google Sketchup to export a model as a Marathon map file that can be played with the Aleph One game engine.

Licence

Notes for version 1.0.1:

This is a working version of the script the Professor helped me fix over email.

Luckily it was found in system files of old computer. It is now safe and sound.

This plugin replaces all Pfhor textures with a combination of the Marathon 2 and Infinity versions into single textures. The result maintains Marathon 2's bright colors, and adds many details from the Infinity textures.

The plugin will work with either Marathon 2 or Marathon Infinity Shapes (or any scenario that leaves the Pfhor texture set unmodified).

Questions, comments, bugs? Post on the Pfhorums.

Notes for version 2.0:

Version 1.0: Initial Release

Version 2.0: Plugin expanded to replace the entire Pfhor texture set, various improvements throughout the pre-existing textures.

Replaces the 2d scenery sprites with 3d models in Marathon 1

Note: works best in shader mode.

Make sure bloom is turned off!

Obviously some errors can't be avoided, but I have done my best to smooth over as many bumps as possible.

Notes for version 1.2:

-Replaced the escape pod model with a much better one

-Changed the pfhor egg to be more like the original (an egg)

For mapmakers testing their terminal scripts, this Lua console command will set the current level's completion state to "finished". Install this solo Lua plugin and type 'complete_level()' in the console to satisfy any mission requirements.

Note: the command may make the level unplayable. See the included Read Me file for more information.

An alephone plugin that can be used to help you determine if your map has enough differential shading. It will turn all of the floors, ceilings, and walls solid green. If you do not have enough differential shading, it will be difficult or impossible to look around and see the architecture of your map.

If after turning this plugin on, you can navigate your level easily and see all of the architecture, your map has adequate differential shading.

You will likely need to disable other texture plugins and any others that run lua like visual mode when using this plugin.

This is a Collection of Texture upscales for Marathon, all textures have been upscaled by a factor of 4 with the intention to keep as much detail as possible.

This is a little weekend project that ended up taking a few more days than planned, please be aware that some textures still need some work but in general im happy with the current quality of most textures.

Enjoy!
