The mod is released : viewtopic.php?f=119&t=5341
Hello everybody. I'm a long time viewer, first time poster.
Deconstruction of Davo's Creature Cells mod and random guess'n'check led to this.
This mod replaces the Maxis Cells with user made cells. Currently in development and expecting a release within a week(assuming I don't get distracted by something shiny).
I don't think anyone has done this yet since I've read lots of posts saying that replace a cell with a non-maxis creation is impossible. If someone has done it, feel to post a link.
Here are some pictures of other cells and some notes on the Mod's development: http://imgur.com/a/hP3bk
