A physics-to-JSON and JSON-to-physics utility that creates human-readable output useful for version control systems such as git. You can then edit these JSON files using a text editor, another program, etc. and turn them into physics files. Also included are utility scripts for:

• viewing differences between git commits for physics, between any two non-tracked files, or between some mixture of these
• retroactively building a parallel set of commits for a JSON version of one or more physics files' existing history
• automatically generating JSON for every committed physics file, bundling the JSON into the commit

Source code and binaries are available on my website; also available there are signatures for individual binaries. I recommend using them to verify whichever you might run.

For verification purposes, here is my public key fingerprint:

A set of remastered sounds for AOPID: http://simplici7y.com/items/aleph-one-pathways-into-darkness

These are 6 dB quieter than the originals (an attached text file explains why), but also significantly less noisy, much crisper due to the addition of higher frequencies that were absent from the originals, and in some cases free of substantial audio flaws like 60 Hz hum on a lot of the Headless sounds or digital clipping distortion on some of the explosion and weapon sounds.

Note that most of these are not exact reconstructions of the missing audio data, but best guesses that I put together in iZotope RX5 Advanced; in a few cases, however, I was able to use the CD-quality audio sources. Also, make sure you have 16-bit audio on, or you’ll get the original sounds. I also suggest pairing these with W’rkncacnter’s HD AOPID graphics for best results: http://simplici7y.com/items/hd-aopid-graphics

Enjoy!

Port of the Trojan M2 HUD to work with the latest release of Trojan for Aleph One. Fills the screen more than the original M1 HUD, but not as much as the Trojan Fullscreen HUD.

Note that there is a known issue with the Alien weapon not connecting to the right side of the screen. See https://github.com/Aleph-One-Marathon/alephone/issues/222

A medium-sized EMFH map inspired by the M1 level Bob-B-Q. The "trenches" in the middle of the map raise to the upper level every minute, changing who has the high ground. There's also a secret switch that reveals every two minutes that'll temporarily flood the lower level with lava.

This is the first map I've ever shared, so please give feedback; Assuming I don't lose interest in a week, I'll be happy to patch it.

This is a collection of maps I used to play in middle school in 96. I unfortunately don't know who the original author is. Somehow I have managed to hold on to the file this long. Where some packs are hit or miss, this whole pack is pretty solid.

This is a version of the Fullscreen Corner HUD that is made to work with Trojan in Aleph One. It moves the HUD to the lower left corner of the screen and allows for fullscreen mode without any black bar.

The HUD graphics are from the M2 port of Trojan, which doesn't take up the full screen like the original does.

Notes for version 1.2:

Removed the alternative shapes file since the gap happens even without my fullscreen plugin.

This script adds some basic quality-of-life improvements to Marathon's default cooperative play:

• Shares weapon and ammo pickups between players
• Restores previous weapons and ammoes after respawning
• Respawns players at the last pattern buffer any player activated
• If the respawn point is under lava or goo, falls back to start of level

Select "Use Netscript" while gathering a co-op game, and choose Basic Co-op.lua as the netscript, to activate it.

Requires Aleph One 1.3

Notes for version 1.2:

Changes:

• Really fixes chip issues. Should work with original Marathon as well
• Uses the last pattern buffer any player used as the new respawn point.
• Falls back to start of level if the respawn point is under lava or goo

Here it is, at last: Marathon TROJAN. Now compatible with Aleph One (1.3 or newer), this uses the native M1 files to deliver the original, unaltered experience we know from the 90's.

M1 compatible fullscreen HUD plugins will work with TROJAN if you don't want to use the included Classic HUD plugin.

Additional files include the Weapons Pump Patch, FAQ, Manual, Spoiler Guide, and read me's from older versions of TROJAN.

Special thank you to Hamish Sanderson for giving us permission to distribute this re-release of TROJAN. Enjoy!

Update 3/3/25 - You can also find a Trojan standalone edition here https://hhas01.itch.io/trojan-se

"James’ Trojan AO scenario (2020) is a highly faithful warts-n-all port of the original M1 Trojan. This was important for historical preservation of early Marathon history, but not a great gameplay experience itself.

Trojan Standalone Edition (2021) made numerous fixes and enhancements to James’ scenario and customizations to the engine code. That’s why it’s released as Standalone Edition, not an add-on."

"What a hoot! If you enjoyed revisiting Earth in Tempus Irae, you're going to really like your "Vacation In Vilcabamba". The mapmaking is excellent and more than sufficiently puzzly, the new textures are gorgeous, the terminals are completely proof-read, the AI is moderately twisted, and the monster placement is quite good, with a new baddie for you to wrestle with. My only disappointment was that it was only one level; I finished it cheering for more." Description by Rigger

Created by Daniel Thomas

I have applied the old Mac patches and converted to files that modern Aleph One will read. Enjoy! -Shappie

Almost Transparent Blue is a single level for Marathon Infinity with an emphasis on intense close quarters combat and creative use of Marathon's air movement.

I first began work on this level because I kept worrying about how the kind of combat I enjoyed would be received by the wider community. I created this level to indulge the kind of fight design I enjoy, where concepts like bullet herding and crowd manipulation come into play and the player is surrounded by enemies. Over time I decided I wanted to find the elements of challenge gameplay that are unique to Marathon's mechanics and aren't possible to recreate in other classic fps games.

If this understandably isn't appealing to you Easy and K should offer a relaxing experience for the most part.

Total Carnage is balanced for my enjoyment. Maybe you will enjoy it too :)

Due to a bug with raised dynamic limits, currently trying to load saves from this map after quitting the A1 application will crash A1. To fix this, begin a new game on the map, then exit to the main menu and load your save.

may require Aleph One 1.3 as I haven't tested with 1.2 and don't know when dynamic limits were changed. additionally software mode will experience some visual bugs with invisible liquids.

Notes for version beta 1.1:

tweaked player starting position to make the jump to AR easier without straferunning, tweaked item placement in final area to give the player a better cue for when to shoot at the beginning, hopefully fixed a monster bugging out in the same area

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.

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.

Comment: - 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.
