Excellent summary of the information!
I can still repeat what Qwerty said about the cheats in the second game:
heroes2.exe /nwc
in windowed mode, a menu appears with all the codes for Heroes II, including infinite movement.
Another unit from the second game comes to mind - Djinn (halves the stack).
In my opinion, it's the strongest unit for offline play.
Thank you.
I've now organized the scouting - it's still an integral part of offline play.
Now, about the units. While I'm gathering information about useful units for offline play in Heroes III, what else can we remember about similar units in Heroes II (besides Djinns)?
