I recently had to reformat my PC and lost all the mods I was running in Fallout 3. One of the mods in particular make NPC's and the Player in-game cycle between these animations while holding a rifle. More importantly, they kept this posture as they walked. I know Umpa's Groovatron has these but they are only static animations.

I got these pictures from Google images but they are very close to the animations that came with this mod. Any help is appreciated. Thanks!
