Fallout 2 - Unofficial Fan Patch @ NMA

The final Fallout 2 fan patch from Killap is available at NMA, also incorporating (I believe) Timeslip's awesome engine tweaks.  Here's their newsbit, which contains all the links:

This patch has been in production for several years now and it fixes well over 800+ bugs left in the game since the official 1.02 patch. I suggest using this installer version as opposed to the manual one since the installer will do everything automatically for you. If you want to do things manually though, go ahead and grab the manual rar version. I hope you enjoy the best Fallout 2 experience yet!
