Portal 2 PTI Wiki

BEEmod is (as best said by it's GitHub description) "a Portal 2 tool which allows you to change what items are in the fixed-size editor palette, as well as the style, music, and other settings". Installing this mod allows users of the Portal 2 Perpetual Testing Initiative Puzzle Creator to use many more testing elements and test styles.


BEEmod comes with a list of testing elements that it grants the player access to, the most notable of which have a place on this wiki.
