where can find the different edition?

I assume you're wondering where the Elite edition is?

Well I'm stumped. I can only assume the author got ahead of himself when writing the http://www.fallout3nexus.com/downloads/readmes/RH_IronSights%20-%20FOSE_readme.txt, because according to that, the status of the Elite version is still Incomplete - and is nowhere to be found...

I would go and badger the modder on his mod page: http://www.fallout3nexus.com/downloads/file.php?id=6938

:shrug:

But people say that it is not compatible with the elite I read the different mod descriptions
