Hi guys just started up skyrim on 360 and got an update for some reason it was small and i have not noticed anything different, anyone know what this was for ?

Horse combat. It's update 1.6, there are many threads for it.

Horse combat.

Get a horse.

Kill things on that horse.

I command you.

It's patch 1.6.

If you use the "Search" bar, you'll find a ton of threads about it, OP.

Basically this. You can use bows and melee weapons but not magic or shouts.
