That links you to the full version of the mappack. There are still a few things missing *cough bonus stages cough*. Yeah, whatever.
If you don't know how to install this, look at the guide in my signature regarding Mari0. Also, this is to be played with v1.6 mari0.
Have fun, and good luck.
Also, if other people want to post their mappacks here, feel free to do so. Not that there are that many... :(
