XCOM Extended Perk Tree Editor for XCOM Enemy Within with Long War 3.0 Beta 13+
(Complete Perk Tree)
Updated for Long War 3.0 Beta 15. Since this is way faster, I got rid of the old version. You can find the old pages here: old pages
Note that perks created for Beta 14 or 15 (at the end of the list) don't work with earlier versions.
This might work for earlier versions as well, but I don't guarantee anything.
Let me know if this gets out of date and I'll update.
