 Hexcheat:

 In HeroesIII HEX-codes can win the game from the beginning till the end. In
 the beginning of the game set gold to 9999999, then build a market and
 exchange all the resourses. If it's still very difficult to play, then try
 to find the value of some units (I prefer snipers or enchanters). But if,
 for example, you haven't any heroes and enemy is going with 100 archangels
 on your last castle, then try to find the value of the archangels, then set
 it to 1. And then find the archangel's health (very easy to find!) and set
 it to 1, too. What about me, I don't use the codes of the units very often,
 because the game becomes a little boring, I think... But in fact, HEX-coding
 is better, than cheating.
