The Environmental Protection Agency is a location that never made the final release of Fallout 2. EPA Design Docs can be found on The Vault (English)
There are 4 versions of EPA in circulation:
- Chris Parks original release
- Alternative Lifes version
- Killap's Fallout 2 Restoration Project version of Chris Parks original
- MIB88 Megamod version which was updated by both MIB88 and Chris Parks
Chris Parks EPA is true to the FO2 design documents, Alternative Life is Avegas own take on it.
Chris Parks EPA is now included in the MIB88 Megamod and the Alternative Life EPA is included in the MIB88 Megamod as a BOS research facility, with many new features such as "Curing" Lenny.
