Now we're talking about it. Can you use a 1X1 pulg on a 4X4 building to make a helicopter spawning weapon? If it can I'm gonna use it for my Naval Yard, but it would be useful if someone can tell me it's possible. I'm not sure
I don't think that will work. when Upgrade buildings are used, the game engine merely adds the upgrade structure's abilities and the graphics to the "parent" unit, meaning you'll get a 4x4 building trying to spawn hornets.
Also, not all a structure's abilities (such as psychic detection) can be used as upgrades.
