M2I HD Sounds Mod 0.1

djkontraktor on Jul 29th 2020

This is a sounds remaster for Marathon 2 and Infinity. It converts all sounds to 44.1 KHz 16-bit stereo with noise suppression, widens them, equalizes them, and adds reverb and echo at appropriate times.

Notes for version 0.1:

There are a few sounds that need to be adjusted: -S'pht Platform running sound is too loud and sounds like a freight train humping a drum store. -Some looping sounds need proper intro/end termination to remove the transition "popping". This has been fixed already for "Alien Noise 1" and sounds lovely on Acme Station.

Survival 2.0 1.7

Benoit on Jul 28th 2020


I released a new survival script for marathon infinity based on the first one made by MegaByte.

In This Edition:

  • Continuous wave of aliens, rather than round based combat.

  • The number of spawned aliens is capped at 50, in order to avoid AI frozen monsters.

  • Almost every type of monsters are used. They spawn from the easiest to the hardest to fight.

  • Bobs are included to help the player. A random invincibility power up will also spawn in the map to call in bobs when picked up.

  • The script works on almost all maps. Aliens can sometimes spawn in unreachable places but the script will handle this. Just ignore it. The script works better on some maps.

  • Players health will regenerate after some time if they're not taking damage.

The rest of the rules should be the same that in the first survival. Including reviving mates, if everyone dies the game ends,...

Some settings can also be modified in the lua script like regenerating life, bob powerup, dead body boucing, ...

I advise to play in normal mode until 3 or 4 players. It will be hard enough. Major damage is good for 4 to 6 players and total carnage for more.

Warning : Do not host it with HD Monsters Texture or it will crash. The game must load all monster collections and HD Monsters Texture will cause an insufficient ram error.

Also do not host on any maps that are extremely large or small because monster generation is based on the area and size of each level.

Thanks to aquateenhgrfrce for his suggestions and his help for testing the script.

Notes for version 1.7:

1.2 : A survival generator has been implemented. You can now customize the survival by choosing your opponents, your allies, the different levels of difficulty and the probability of spawning for each monster. You will find it in the zip folder with the survival script and the folder "Ressources" containing images for the generator. You need Java to execute it. Place the application Survival_Generator.jar in the same folder that the folder "Ressources" then you can run it.

1.3 : Ask it and you got it. I made updates for the application just for you WindBreaker :D You can now load an existing survival file in the application to make modifications. You can also edit the time of a round. But you can only load survival scripts which have been created with the generator and which have not been manually modified (except for the settings of course) That means you can't load the original survival 2.0 script but you can load the one in the actually zip folder which has been generated with the application.

1.3.1 : The display of the timer after 1 hour of gameplay has been fixed. Thanks HailErdogan to have found that bug.

1.4 : Monsters dead animation has been fixed. If you noticed when a monster dies, his body does not move and can sometimes be frozen, floating in the air. Same thing for the drones/juggernauts which often explode in the air. All is properly working with this version. These corrections also improve the fluidity of the game, that's why I really advise you to use this version.

Addition : a new functionnality has also been implemented with this version. (disabling/enabling in the settings of the script) You can teleport to the plateform you are aiming by pressing the microphone key. You need your oxygen bar full to use it and teleport will drain it. The bar will fill up with the time.

1.5 : Monsters won't spawn anymore in unreachable areas except for maps which don't have hill. In this case, the script will work like for the version 1.4.

1.5.1 :

  • Disconnected players are not displayed anymore with the minimal display.
  • Sometimes the character of a player who get disconnected could stay alive, he now correctly dies.
  • When you generate a script with allies major or minor aliens and play it with an opposite difficulty, for instance, minor aliens with total carnage difficulty, only major aliens will spawn and they won't be friendly. This has been fixed.

1.6 :

  • Minor bugs fixed.
  • Bug with the generator's performance fixed.
  • Added the possibility to choose the number of aliens by setting the options in the lua script.
  • The name and the health of the target you are aiming are now displayed. Red for ennemies, green for allies.
  • The score's calcul has been reviewed. It increases by dealing damages to ennemies and killing them. It decreases by dealing damages to allies and killing them. Revive a mate and kill yourself will also change your score.

1.7 :

  • Added missing monsters "Tick" in the generator (minor, major and kamikaze) as suggested by Tycho X.
  • Added possibility to group monster families by team in the generator by right-clicking on a monster to attribute him a color (see screens). Monsters with the same color are on the same team. Which means enemies or allies with different colors will fight each other. If no color are attributed, it works by default "Ally vs Enemies". This was also suggested by Tycho X.
  • Monsters teleport in the map instead of spawning from nowhere.
  • Small other improvements with monster spawning.


  • If you want to use the generator to make your own script with the script's latest version, you obviously need to use the latest version of the generator.
  • If you want to upgrade a version of a custom survival script you made, just load it in the generator and regenarate it to be upgraded to the last version.

Since the original game doesn't allow more than 32 active ennemies in the same time. I recommand you to change it. Especialy if you play big maps with a lot of aliens or if you want to change manualy the number of aliens as explained in the 1.6 section. For that, go into your marathon folder, script folder, open marathon infinity.mml with your text editor and replace the number paths value = "32" by the number you want (power of 2 and max 512). If there is no such thing in the file, you have to add it yourself like this:

<dynamic_limits> <paths value="128"/> </dynamic_limits>

inside the <marathon> tag.

Let me know if you find some bugs or if you have suggestions.

Answer to helviusrufus: Haha indeed. Sorry for that and thanks for you feedback. I focused on the generator and forgot to upload the new version of the script with it. You could have still upgrade yours by loading it in the generator 1.7 and regenerating it. I have added the script in the archive but it's possible you don't see it right now if you browser cached your previous download. If so you will have to either wait or download if from a different browser or delete your browser cache.

Marathon 1 Remastered Sounds 1.0

The Man on Jul 27th 2020

My long-overdue remastered Marathon 1 sounds. They should be noticeably less noisy, crisper, and (in some cases) less distorted than the originals - even more so than my remastered Marathon Infinity sounds, since all of the original Marathon 1 sounds were 8-bit.

Includes a readme with a bunch of (hopefully) useful information, but you should be aware of a few caveats before downloading or using these:

  • These will only work with Aleph One, not the classic Marathon app.

  • These will only work with the classic Marathon files, not M1A1.

  • You will need to quit and reopen Aleph One after selecting these in your preferences.

  • These are half as loud as the original sounds. You may wish to adjust your music volume.

Should you have any other issues, please let me know via one of the forms of contact included in the readme. Beyond that, enjoy!

Notes for version 1.0:

First release.

M1A1 Fullscreen Corner HUD 1.0

Shappie on Jul 27th 2020


This is a slightly modified version of Hopper's M1A1 HUD. It moves the HUD to the lower left corner of the screen and allows for fullscreen mode without any black bar. This should work for any Aleph One scenario, including M1.

I also made a few small edits to the HUD itself for aesthetics and transparency.

Thanks to wrkncacnter for the additional scripting.

Fullscreen Corner HUD 1.0

Shappie on Jul 18th 2020


This is a slightly modified version of Hopper's M2 Default HUD. It moves the HUD to the lower left corner of the screen and allows for fullscreen mode without any black bar. This works for any non-M1 scenario.

Thanks to wrkncacnter for the additional scripting.

Phoenix Falling 1.3

Shappie on Jul 18th 2020


Phoenix Falling is a large M1 scenario of 44 levels featuring a new story with new characters, weapons, creatures, sounds, shapes, and more. (48 with secret levels and one network level)

Please keep in mind - there are bugs in this release. Most of these are caused by running the game in the Aleph One engine, which did not yet exist when the scenario was created. This used to be run with the original M1 engine.

Some of the largest known bugs are related to shapes not rendering correctly with chairs, tracer rounds from the brass gun, the weapon display in the HUD interface, and most of the new creature animations.

Repackaged for Simplici7y with permission from the Phoenix Falling creators, Matt & Andrew Schenk.

Notes for version 1.3:

This version has a fixed Map file that should allow terminals to function in the vacuum levels.

Operation Tantalus 1.0

Shappie on Jul 17th 2020


"A 19-level solo masterpiece, with new sounds, shapes, terms, physics, bobs... and it's totally non-linear (you decide what order to do the levels in). Brought to you by the folks who did U.S.S. Raider, Athens Outpost, and the Marathon's Story page."

This scenario has been converted to an Aleph One compatible format and repackaged for Simplici7y.

Marathon Evil mml 1

The Last Nakh on Jul 15th 2020

Like with the Marathon Red mml which I uploaded recently, the mml included in "" is not the same as if you were playing the original Marathon Evil.
In this case, it is very different.

For example: the assault rifle in Evil was a “MOW-MDN/36CM ASLT-WPN”, not an “MA-90E”.
Those other names have been distributed for years, ever since Aleph One SDL was a new thing … does nobody else here play with the authentic Evil mml? Pardon me if I don't know whether some other total conversion named the fists a pair of “steel manacles”, and that the person making the old mml was confused, or whether they decided to invent new names when they wrote those old mml files.

So, if you wish to play Marathon Evil with the original text strings, you'll need to completely replace the "Evil Strings.mml" file which was included in the aforementioned "" package.

When you do replace the old mml with this one, there is one more thing you'll need to do: either rename the "Music.ogg" file to "Music Accursed.ogg" or change the string with index="10". In this mml file, the strings for default filenames were made for those who have all their scenario assets together in the same folder with the Marathon Aleph One executable a-k-a app. Those of us who do so disable individual mml by moving files to a different folder where Marathon Aleph One doesn't load them. You gain more flexibility with your scenarios if you do so, and you only need to ensure that filenames do not conflict.

Marathon Red addenda 2

The Last Nakh on Jul 15th 2020

I don't know if these are available elsewhere nowadays, but the copy available at "" has incomplete mml.

So, here are some mml tags to make your copy more like the original Marathon RED. A few things are changed slightly; those are marked with a <!-- --> tag.


Notes for version 2:

When previously editing this for upload, I carelessly omitted the </marathon> closure. Oops, I'm an idiot and a shame to the Nakh legacy.
Also a few small changes to blankspace or comment tags.

Narrow Mountain Path

Exy on Jul 14th 2020


Narrow Mountain Path is a weaponless platforming map combining tricks that let the player climb stairs higher than .33 WU and regular fast precision platforming. If a player gains a bit of height off the ground they can put their feet within .33 WU of a higher ledge and climb it, again giving them extra height they can use to climb subsequent steps. Using air control you can also steer off and onto a ledge so that you gain a height boost as if you were climbing a step which makes longer than normal horizontal jumps possible.

Despite the special trick emphasis I've tried to make this a flowy fun map to play through without falling or speedrun. Included in this download is a speedrun film and a film showing some more beginner friendly routes. A second version of the map with 3x health and an AR can be reached with level skip for more speedrun fun.

Straferunning is required to beat this map. To strafe run, press your forward + left or right strafe key to move faster at a slight diagonal.
