Desolation (Zan) addon - Doom

Desolation, the 12-level megawad and sequel to Damnation is now up on idgames.

To start things off, the story takes place shortly after the events on Kronos in Damnation and follows the surviving marine as he encounters the Stalwart station and the nearby ice planet, Thanatos.
The feel of the Wad is similar to that of it's predecessor, but the gameplay is a little different:
It is less chaotic and "bold" than Damnation, with the levels presenting more traps and mind games while being more horror focused. Most areas are considerably darker, and you might find yourself in the midst of some hard encounters within the first couple levels, as the Wad slides more toward the difficult side.

The Zip is 56 MBs (mostly due to the 64 Ambient Sounds and 20 .ogg music files which make up the levels, and yes, much smaller than the huge MP3 files in Damnation), and contains Doom - Desolation.rtf, Desolation.txt, IDTEX.wad, q2tex.wad, cc4-tex.wad, and the usual skulltag_actors.pk3 and skulltag_data.pk3 (all which are required for the Wad to run properly, excluding the .rtf file) in addition to the Wad itself.
Unlike in Damnation, Brutal Doom is not a necessity and it's just as fun on normal Doom, though you may notice imbalance in ammo counts. I managed to implement Co-Op support as well, so go ahead and try that out with someone if you want.
It uses some of the Skulltag monsters/weapons/items throughout, which is the primary reason I haven't made a GZdoom version for the Wad, though if enough people make requests for one I'll probably go ahead and do it.

Now to close things off, I'd recommend you read the .rtf file that comes with it if you want more details on the Wad and are interested in the story.
The installation instructions are as follows: Just extract the files in the .zip (though you can ignore the .txt and .rtf file within) into your Zandronum skins folder, or just select them all and open them with your zandronum.exe, and play.
Let me know if you have any problems with the Wad (technical or gameplay wise) and feel free to report any bugs.
