Doom 2 : Stronghold - On the Edge of Chaos

[Manibrandr System]

I have been playing Doom 2 mods for a while, and I came across this gem of a mod. It pretty much turns Doom2 into Unreal Tournament's Assault/Onslaught mode. The best part is that the mod is moddable.

While the mod is made for GZDoom and Skulltag, it only works with Skulltag in multiplayer. If this goes over well, you could put in this Stronghold enhancer mod which multiplies the enemy count by 4-5x and adds in new enemy types.

So what do you need?

A Copy of Doom 2. (It's just to obtain the DOOM2.WAD file. You can get it on Steam for 10bux.)
The latest stable build of Skulltag. (Put the DOOM2.WAD file into the Skulltag folder.)
Stronghold Mod v1.0. This goes into the Skulltag folder too.
(Optional)The Stronghold enhancer addon. For if the regular player count reaches 5 or more, also goes into the Skulltag folder.

Once everything is downloaded, you can even play it single player offline. However, I recommend using GZDoom for single player, since GZDoom is more optimized for Single Player, while Skulltag is better suited for Multiplayer.
