Hello,
I tried to hack dota 2 and i found that it uses the value of 0.5 for the normal zoom, and you zoom the map out, its value ccomes to be 1.
You can use cheatengine to search for that address (float).
But you should be carefull because the last time i got banned because this game detects if it is debugged.
If anyone knows how to bypass it, please share your idea.
Good luck,
SieuTruc
