An ambitious project started by respected and prodigious Fallout modder killap two years ago is now finished, The Fallout 2 Restoration Project:<blockquote>The day of release has finally come. It has taken me about almost 2 years to get this complete and yet I still believe I can find stuff to add. The purpose of this mod is to add back into the game all the content that was originally planned by the Fallout 2 devs. You will find about 6 new locations (some quite large, other smaller) as well as a few new areas to old locations. In addition, almost every town in the game has new content whether it is new characters, quests, or items. Playing this will definitely be a new experience. Completion of this expansion would also not have been possible without several individuals who I thank in the readme of this mod. Big thanks to all of you! </blockquote>Link: Fallout 2 restoration mod installer version.
