I've finally started a little bit of work on modding Fallout 3. So far I've finished up making a seamless body mesh that will be perfect for Rocky's body type. Whether it'll actually work in the game right now is uncertain. I haven't had the chance to test it yet but it looks fantastic if I do say so myself. As far as I can tell, It's also possible to make costom heads in Fallout 3 as opposed to Oblivion where that was nearly impossible. If all goes well, I might actually be able to have some screenshots soon.
It may also be possible to include Axel in the mod as well.

I'm gonna finish up the Oblivion mod too! I promise!
