Here are a few add-ons or extras that I have created for the Balance Mod. Be sure to note any special notes that I have posted as some items are not compatible with existing save games or other files.

Balance Mod Pollution Events v1.04 Obsolete!
The Pollution Events introduces the concept of pollution to the Balance Mod. Each turn, colonies that contain primarily industrial facilities will see their conditions decrease slowly over time. The rate that a colony will see its conditions deteriorate will depend on the number and type of facilities present and planet size. Log messages are generated whenever a planet drops from one conditions level to another. There's also a small happiness penalty. Only Climate Control Facilities can repair the damage and reduce the effect of pollution.
