EDIT: Use the download in my other thread for the current most stable version of this mod.
Here's my second ever mod. This is a mod in which the existing lifeforms find new purpose. Expect to find new lifeforms and new uses for existing lifeforms.
It was created with an eye for replayability: A number of the quests share keys, and thus will not trigger in the same game. You have to play quite a few times if you want to see everything.
