ZenMPack is a simple vanilla doom2 compatible mappack.
The amount of maps in the final version depends on how lazy I'll be and how much time I'll find but I'm looking forward to get 10 - 15 maps done, they are all going to have multiple difficulties and the first few maps are going to have deathmatch (all the deathmatch maps are finished and playable in the demo). I've been pretty lazy and only made 5 maps the last half year, from which MAP01 had to be completely recreated because it didn't fit with the other maps very well.
It will probably take me another year to get this project done.
Right now I have MAP01 - MAP07 finished with different difficulties and you can Play the five map demo wad I just submitted on gamebanana a few days ago.
Spoiler: Nine 640x400 screenshots (Taken from the demo wad with crispy-doom)

(I hope I didn't broke any rule this time, read through them all and they feel kind of strict... tried my best to follow them)
