-Fixed bug where UBNS respect would decrease to 10 if you reload your initial save.
-Fixed problem with Pluto's AI on the Oil Platform.

RESOURCES:
-New object and texture: ruinsBrick.
-New object and texture: shelter2.
-New texture: tinWallC.dds.
-New "fail.wav" sound (old file format was weird).

STORY FILE: (requires starting a new game)
