NHF – new heroes for Heroes V 3.1.

Is it possible to add models and heroes from the 240H mod to the new update of NCF (NCF_E)?

NHF :(

It is possible, but it's probably not a good idea. It contains models from all over the world, but there are too many that are of low quality, and some are even in the form of creatures =(
Besides, people are already working on the models, as can be seen from the discussion above ;)
