Marathon Infinity

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.

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.

Marathon Apotheosis 0.9

Shappie on Jul 13th 2020


A 22 level single player game with brand new terminal art, weapons, environments, characters, and a story fleshing out the Marathon universe.

This scenario had become unattainable save for a single place, the Marathon Total Carnage Pack. I extracted and repackaged it to upload here, so everyone can access and enjoy this incredible scenario.

It is technically "unfinished" but only in the sense that it is missing some polish. It is essentially complete and you can play through the entire scenario without issue. Read the read me file for more information about Apotheosis.

Special thanks to Hypersleep.

Community/Freeverse Plugin - Monsters 1.3

herecomethej2000 on Jul 6th 2020


CFP is a complete set of high definition textures for Marathon Infinity and Durandal. Based on the original Freeverse Marathon 2 Durandal XBLA textures, these have been further enhanced by the Alephone community with glowmaps and made to support Marathon Infinity.


Freeverse, Hopper, Treellama, TheDoc45, General Tacticus, J2k, Spurious Interrupt, Tfear7

This is the monsters portion of the plugin.

Installation: The downloaded file must be decompressed and the sub zip files moved to the appropriate plugin folder. The reason the plugin is broken up is for improved performance while still having the benefit of being compressed.

Note: Alephone doesn't handle overly large compressed plugins very well, especially on OSX. This is because Alephone would have to decompress the entire monster set just to get at the relatively few sprites it needs for any given instance. By breaking the plugin up into multiple plugins for each monster type, it only has to decompress what it needs for an instance.

Remastered Sounds for Marathon Infinity 1.1

The Man on Apr 10th 2020

I have remastered the entire Marathon Infinity sounds file. The most obviously noticeable changes should be that many sounds are much less distorted (with the side effect of being noticeably quieter - adjust your system volume as needed), and sounds will feature approximations of upper frequencies that were missing on the originals. Many sounds that were originally 8-bit (a good example is the “got item” sound) will also be much less noisy. Detailed information on the changes is included as a .pdf with the download.

This should work with any Aleph One scenario that uses the vanilla Infinity sounds. It should also work with Marathon 2, provided that you run it on Aleph One - it probably won't work with the vanilla Marathon 2 apps for either Windows or Mac.

Important: YOU WILL NEED TO RESTART ALEPH ONE AFTER SELECTING THESE SOUNDS. (Bold and caps so you don’t miss it.) On the plus side, you’ll only have to do this once (unless you move back to the default for whatever reason).

Notes for version 1.1:

Finally uploading a new version, primarily because I’d mixed up the “S’pht Door Closing” and “S’pht Door Opening” sounds. This is because the sounds file itself had them mixed up in the 8-bit sounds slot, which was what I was using to check that I’d uploaded the right versions of everything; and also because ShapeFusion also has them mixed up. (I’m supposing Anvil may also have mixed them up, but I haven’t checked.) In any case, the game seems to want them where the vanilla file has them in the 16-bit slots, so anyone else who wants to make new versions of the sounds should take note: The “S’pht Door Opening” and “S’pht Door Closing” sounds are mislabelled in ShapeFusion. (The mislabelling may also be true of the Pfhor Door sounds; I’d advise double-checking. However, I did not mix those up, because the 8-bit and 16-bit sounds for those are in the same slot.)

The other major change is that I have moved all of the sounds to the 8-bit slot rather than the 16-bit slot. These sounds are all 16-bit, but on the whole, the game doesn’t care one way or the other; it will still play them as 16-bit sounds. This does have one major drawback, though: YOU WILL NEED TO RESTART ALEPH ONE AFTER CHOOSING THESE SOUNDS. (This is in caps so people don’t miss it and complain about it.) On the plus side, you will only need to do this once (unless you go back to the default sounds for whatever reason). I think this is a caching issue with how Aleph One handles sounds, but I’m not sure. The advantage to moving them to the 8-bit slot is that if you accidentally select 8-bit sounds, you will no longer hear silence. Everything will sound really bad, but at least you’ll hear something!

I may also have revised a few of these sounds since 1.0. I didn’t keep detailed notes, so I have no idea what I changed.

Should you have any questions, you can contact me on the Pfhorums (same username as here), reddit (/u/aaronnotarobot), or Discord (Aaron#6608; you will need to be a member of the subreddit Discord – or some other Discord I’m in – to contact me). Enjoy!
