Aleph One (formerly known as the Marathon Open Source Project) is a free and open-source first-person shooter engine based on the source code of Bungie Studios' Marathon 2: Durandal.

The project commenced in early 2000, when Bungie released the code shortly before being acquired by Microsoft and spurred the fan community to further develop it. Since that time, Aleph One has become a successful project in terms of development and community support. Most modern-day and die-hard Marathon enthusiasts use Aleph One due to its enhancements over the original games and the fact that it is playable with today's platforms. Its name is taken from the second infinite cardinal number in transfinite arithmetic and references Marathon Infinity, the final game in the Marathon Trilogy (the "smallest" infinity is aleph-naught, or aleph zero).

Initially, Aleph One was only compatible with Classic Mac OS (even though a version of Marathon 2 had been previously produced for Windows 95), but it has since been modified to work with SDL across a wide range of various platforms, including Mac OS X, Windows, Linux, BSD and BeOS.

I'm on the lookout for Aleph One for use on Mac OS X Tiger for PPC Macs. Preferably that can play all 3 commercial Marathon games, but will settle for Marathon 2 and Infinity. My search fu has come up empty.

For 9.04 is needed

I've added an early 2001 build, which I think runs on Mac OS 8.6 and above (haven't used this since about that date so I'm uncertain of it OS limitations). Pretty sure 9.0.4 will be OK tho'.

Sourceforge has some later classic builds that you also may want to try. I haven't tried these and don't know if they'll run in 9.0.4, but it may be worth investigating. The Apr01 link on that page appears to have the same version that I've placed above, as their respective checksums match.

@mrdav: I think different (Aleph One) Player versions could all be added to this page, with a small note for each one's system reqs. I know I have an OS 9 compatible player archived somewhere, just a matter of finding it Wink

I have a file (AlephOne-20120514-Mac.dmg) that was originally uploaded here in 2012. It is version 1.0.2. The dmg also contains a copy of the Marathon Infinity application for PPC. Do we want this here? Or is it here but moved to another page?

I upload aleph one 06-20-2015 is 1.2.1. Universal for PPC and intel. This works for mac os x 10.4.11 and mac os x 10.5.8. It might work on later 32 bit intel and mac os 10.14 mojave. The newer version 1.3 for 64 bit intel on aleph one webpage.

Hi Scott. Yes upload it. Under the terms of the Aleph One GPL3 license this one is OK to add here. Even earlier versions would be good, too. I think I have old copies that run on OS 9.x

This link to marathon aleph one is not working. I have same link too.
I don't know why the website is not working.
It shows this on Safari 5.0.6. The website is down two days.

Safari can’t open the page “” because the server where this page is located isn’t responding.

Do anybody know why website is not working ?
Website is gone and they did not have money to keep this website running or they took website offline to updated.

I got it to work on 10.3.9 with Highres-Textures on an old AlephOne from 2008!

I'd like to eventually archive all of Aleph One for Mac OS and PPC Mac OS X, including all available builds and source code. And if I do it before everyone else, I'll make sure to upload them here appropriately. For now, let us hope the sourceforge downloads won't go away.

That would be nice.
These are "onefiler" but do not work on my G4-Mini on 10.3.9 =>
M1 on my setup is very nice, but I discovered that it is the FanRemake. The Textures look fantastic (as good as the linked ones above, but the game does only work on 10.4+)
My M2/M3 has the original Textures and therefore does not look so good. (blurry). So I will try to combine the files(textures/shapes?) from the later ones to my AlephOne Engine from 2007. Hopefully this will work.

Perhaps some of the stable released versions going back to when it was first released, should be added to this page.

But is 10.4+ I have an old Aleph one 2007 that works great on PPC 10.3.9 on my MacMini.

Yeah, all in all, they're not exactly the friendliest community (though I have to admit I did add fuel to the fire when I insulted back). In fact (despite Marathon being originally a Mac game) Mac users would probably be better off with the Doom community when it comes to harmony.

all I got were a bunch of insult responses, telling me to buy a new computer.

Insults are counter productive and only aid putting off a person's support for a project. Its a pity they allow such behavior there. Well, on the bright side, there's little chance anyone is going to tell you to "go buy a new computer" around here Wink

I found out the the new Aleph one required mac os x 10.7 or greater on intel. Aleph one 1.3.1a version is intel. Aleph one 1.2.1 is last version works on Power PC.

It's worth noting that the current beta releases require 10.7/Lion or later. I tried asking them to see if they'd add at least 10.5 & UB support by the time of the final release but all I got were a bunch of insult responses, telling me to buy a new computer.

Sorry mathieudel. I want in!! Sign me up.
I've setup homebrew on my wii, but that's as far as I've gotten. Add me to the google group when you get a chance.

For those of you that are both fond of this game and the happy owner of a Wii, I've started a while a go to port Aleph-One to it : It's not really usable right now, but I hope to improve this !

For those of you responding to the first filter that also have dev skills, you may help me complete this project : I'm stuck by start-up crashes, probably due to sound engine, and would appreciate some hints !

Last known Mac OS 9 version still available from this Sourceforge link (2008), possibly an unstable release. Sourceforge's links to final releases for OS 9 are here (2006).
