Either your game bugged out or you're doing it wrong.
Alduin is killable, even very much so. I haven't tried iron arrows, though, as I prefer a maxed out blade, some epic magic or some of those handy shouts.
If it's really end game we're talking about here, as you can't possibly kill him any earlier, the only things I can think of are:
- did you bring the valhalla bunch with you?
- did you get rid of the fog?
As far as I remember, nothing much happens really as long as the fog stays there. Well, I suppose you just die, but I haven't tried that one out yet.
