So it’s been almost a month and I still can’t find any mention of how Mac people can get their Action Doom 2: Urban Brawl on. I spent a few minutes last night downloading everything and putting it in the right places. Here’s how you can join in. All the items are free. You will need an Intel Mac [for now, at least] to run ZDoom.
Get the latest ZDoom build from this forum thread, the epicenter of Mac ZDoom development. [EDIT 20090923: The download link on the forum post is currently unavailable; check there for the most current version, but here's a mirror of the one I used to get this working.] Ignore the bleatings of “Get a real computer” from entrenched Winbags.
- Unzip the archive and put ZDoom in Applications or wherever. Start it once and note the plaintive wailing that you’re missing an IWAD:

Get an IWAD so ZDoom will run. I used the Freedoom Complete IWAD. Take the doom2.wad file from that archive and put it in [your home directory] > Library > Application Support > zdoom. You just need that file and it needs to be in that folder, not a folder inside that folder.
Get Urban Brawl from Mancubus. It comes in an archive with a bunch of other files that make it ready to run on a PC. The only file you need is action2.wad, you can scrap the rest. [But while you're there, you should grab Action Doom 1 too.]
Okay, now start ZDoom. Did it complain that it couldn’t find a Doom WAD? No? Great! You put it in the right spot. Now click on “Show WAD Options,” click “Add” in the tray that slides out, and navigate to whereever you put “action2.wad.” Your WAD options should look like this.
Click “Launch” to start busting heads. If you get a terminal window, you probably chose more than one WAD file. You gotta pick one at a time.
I don’t know how well this will work with other Doom source-ports like PrBoom, because the author clearly wrote it with ZDoom in mind, or else I’d try it with the Wii too. Also, there are some dark spots I’m not sure are supposed to be so dark, but I played up to where !SPOILER! Haggar joins you last night and it was very very playable. Nonetheless I would love refinements from the audience, if there is one. I might have just packaged it all up myself, but these components all come from completely different sources and asking permission is tough.
Feel free to ask questions here in comments, I will try to reply [in comments] as time and intelligence permits.
EDIT 20090924: Updated link to Freedoom IWAD — thanks Gary!

It do not load my .wads =/

Hey, David — thanks for the screencap, it helped. You’re putting all the files in an Application Support folder, which looks
You need to put
Zdoom OS X.appin “iMac/Applications.” Then, take that zdoom folder out of “iMac/Library/Application Support/” and put it in “iMac/Users/david/Library/Application Support/“. Yes, there are two folders with the same name in different areas of the directory system.You SHOULD, in theory, be able to put the files in that one, but zdoom only looks in the one for the individual user account. If you have several user accounts on this machine and they all want to play Action DOOM, they’re going to have to have those files in each user account. There might be a way around this with symbolic links and the
Shareddirectory, but I imagine you want to actually start playing the game in the next ten minutes, not get a Unix lesson.Hey man, great guide, one problem though.. the site for zdoomosx_0.6a.dmg appears to have been down for a while
if you still have the file could you please upload it or send it to my email?
thxxx
Gary –
Looks like the ZDoom crew are working on a new release. In the meantime I’ll see if I can find my binary and pack it up into an archive that doesn’t totally violate its license’s terms for redistribution. Watch this space. [EDIT: Added a mirror to the main article.]
Thanks a lot, man. Finally got it working. Seems the link to the IWAD was broken as well, here’s an updated one.

I’m sorry if this seems to be a bother, but each time I try to run ZDoom off this port, whether or not I have the action or action2 wads in the side bar, it only opens up a window that’s titled “ZDoom OS X Console”, nothing more. Is there something I’m doing wrong here, or is this particular port for leopard and up? I’m running 10.4.11, if that’s any consolation. Thank you for bothering to read through this.
Hey Felix — sorry I didn’t see this sooner.
The port I have says it runs on OS X 10.4 and up. I’ve only got 10.5 and 10.6 machines around here but I’ll try to rustle up a 10.4 machine or maybe set Tiger up in a VM and see if I can duplicate. Unfortunately I’m pretty busy with life stuff that keeps me away from keyboards, but I’ll take a shot at it in the next week or two.
There appears to be a new source for ZDoom builds, so it might be time to update the post anyway.
