What it does

This mod fixes in game errors and bugs in Fallout 3 + all DLCs. It's designed to also optimize FO3 with decompression for better performance. Cut content is reviewed/restored only if fixable and able to blend into the game perfectly. Think of this patch as it finishes coding the game since FO3 is a very unfinished game.

Other Thoughts

Before releasing v3. 0 I backported Tale Of Two Wastelands fixes from scratch and revised everything v2. 3. 2 of this patch in comparison and tested everything I could think of along with some testers. Went through all the reported bugs in the bugs tab. Lots of help from Roy (former TTW project lead) and endless hours of work from the Tale Of Two Wastelands team. Please go there when you have a chance and thank them for all the work they did. I personally no longer experience any crashes anymore. This is extremely impressive compared from when I used to play FO3 encountering crashes constantly. Please enjoy and be fortunate of everything that's put into this.

Important Note: Please do not edit the Fallout 3 + DLC ESM files and do not edit this patch or you're asking for things to break in your game. This is only designed for the English version of the game.
