TGrantOut

tGrantOut (named tGrantWorld on the local map) is a test cell in the game files of Fallout 3.

Layout
The cell has its own exterior world space. There are puddles of water and a blasted city ruin containing constantly cycling special animations. There is a laser rifle and a Fat Man on the ground. The "Grant" in the cell name is likely referring to Grant Struthers, the game's gore and special effect artist.

Appearances
tGrantOut appears in the game files of Fallout 3 but should not be considered canon because it is a test cell.
