@**zahar0z** - that's really cool! This is a very useful mechanic... it can be used to add additional upgrades and alt-upgrades for logically related creatures from NCF (with parameter adjustments as needed)! Personally, I think the gameplay will become much more diverse, and for example, completing campaigns or scenarios, or even just well-known maps, will become more interesting, because essentially it will be a completely different game! In short, as they say, respect and kudos!
