Heroes 5.5 WarGame Edition - Tactical Edition.

Hello everyone. I have a really pressing issue. The game desperately needs fog of war for heroes; it would add more hardcore elements to the gameplay. Is it possible to implement fog of war so that the map is visible, for example, around the hero or captured buildings, while the rest of the map remains hidden behind the hero, but with the terrain still visible and enemy heroes invisible? And another question: are these Heroes from /topic/11565/ completely different in version 5.5?
