So, I'm just starting to dabble with modding Zero Hour a bit. Already I've figured out how to limit units/abilities, modify specs of units, and I've also managed to give all USA vehicles the ability to purchase all three types of drones. Nothing's more fun than seeing a loaded humvee with three drones flying around it.

So, that got me thinking- wouldn't it be cool if the Overlord could have all three of his upgrades? But, for the life of me, I can't figure out how to do it. I already found and commented out the same lines of script that I did with the US vehicles, but how do you keep the buttons from vanishing when you upgrade?

Anyone have any input on this?

The code that the Overlord uses restricts it to only having one of the three upgrades. You can, however, combine the effects of all three upgrades into a single upgrade.

Really? How do I go about modifying that?
