Created with Fallout 3 GOTY (Windows Live edition) v1.7.0.3. No mods (including the DLCs) were active, so there should be no dependencies.

Just a game saved before the Vault 101 exit to the Wasteland that allows you to play as a 1 year old. Just finalize your look and stats, then head your vertically challenged bad arsed little self out into the vast, extremely tall world. Created for those who don't want to break out of their playpen on their own.

Here is a recent Kotaku article regarding a person who played all the way through the game as an infant. It also gives you pointers on how to breakout as a young'un on your own.

No radroaches were harmed during the "epic" escape from the vault (babies can't fight, at least until you talk to Lucus Simms in Megaton).

How to install:
Simply unzip file to either
C:\Documents and Settings\USERNAME\My Documents\My Games\Fallout3\Saves (Win XP)
or
C:\Users\USERNAME\Documents\My Games\Fallout3\Saves (Win 7 and later)
(You can always search for *.FOS files as well, just drop the save where the others are located.)

FYI: I don't do requests, so don't ask. :)
