4 comments by Neurological on Dec 15th, 2010

So 2 years has been passed from the mod release and we collected a lot of feedbacks and comments during this time. It was great time during the development and after. It was also a good challenge as we started to develop the mod in late Semptember 2008 and finished for the 22 December. Obiviously in two months we couldn't make a long mod, but our intention was only to deliver something funny and mindless to pass 30 minutes.

This news is for the one that missed the mod and for announcing a Desura release.

"...Actually, the ending left me in tears of laughter...." - Mkem from d3files

Videos & Audio - x - MASS Mod for Doom III - Mod DB

Also, the mod has been reuploaded with the patch 1.1 included in the main package, so you will have to download only once the mod.

"Wrong game DLL API version" - One of the numerous people that still doesn't get the difference between patch 1.3 and 1.3.1.

You can grab the v.1.1. Multiplatform here:

The mod will be released also on Desura, the new Indie and Mod digital delivery platform. So log-in on Desura and download the mod from there if you prefer.

Remember that there is also the official original soundtrack ready for download:

"I've auto voted 10 because I was proud of my self and my teammates" - A shameless Neurological from ModDB

If you are too lazy to download and play, then watch someone else playing the mod. In 2008 Paul's Gaming published on youtube a walkthrough of the mod in 3 parts, you can watch them here:

Paul's Gaming - Doom3 MOD - X-MASS part1

Paul's Gaming - Doom3 MOD - X-MASS part2

Paul's Gaming - Doom3 MOD - X-MASS part3

"i laughed so hard my head turned inside out :D" - jordynh08 from YouTube

For who know japanese, there is also a review over www.game-damashi.com that gives the mod, 5 out of 5:


"...it's Cool, it's Fast, and it's Funny at the same time..." - Ominous from Doom3World

Thats all, download the mod, watch the playthrough or ignore it, but have happy holidays. We would also to thanks everyone that supported the mod in those two years even with insults.

Your version of Doom 3 isn't correct for the mod. You need the ltest 1.3.1.

Thanks for the comment. Yeah we rushed everything to reach the 24 december deadline. The mod is short too infact, but by the time we finished the new models, it was easy to put everything togheter.

The gameplay isn't changed so we had only to put efforts on the assets.

Yes it was sad that it was short, normally it was supposed to be longer but we had a map that crashed and had to remove quite a big part. But except soon another present ;)

10/10, Great mod satisfied my Christmas :D

Humor. you should watch the ending.
Musics. OST worths downloading if you like metal stuffs or ingame BGMs.
New Weaponry. especially Voodoo Doll and Instant Zombies.

Nuke Launcher wasn't as strong as it looks. Explosions were kickass though.
Short. But they made the mod in only 2 months.

Yeah the mod would be better if it was longer, at the beginning the maps planned were 4, with a mountain pass before the castle and the castle itself were bigger with sewers, abig open area section and some others room but with a crash and some others problem, we had to cut something, but we may expand the mod in the future if ppl want to play more.
