Just wondering if there is a mod out there that adds new weapons like spears or throwing weapons to the game without overwriting an already existing weapon type's animations and whatnot? I have seen mods that add guns but as far as the game is concerned they are merely new staff models. So is it possible to add new weapon types to the game or are we stuck with the same basic weapon types?

If Bethesda arent willing to put the effort in to give us weapon types like spears or crossbows or whatever it would be nice if they threw modders a bone and gave us the tools to do it ourselves, I cant imagine spears would handle all that differently from the normal melee weapons, would mostly be just a new set of animations and a slightly altered hitbox.

Weapon types (blade, blunt, bow, staff) are hardcoded and tied to Skills, so no, it is not possible to create a new "type". Which leads modders to faking it. Some have done pretty well in that. A quick search of Nexus found a few spear mods with altered animations. I've also seen a flail mod before. I think it's Deadly Reflex that has the throwing weapons.

It's nice to dream but Beth is not going to give us the ability to do this either. They've stopped supporting Oblivion 4(?) years ago.
