I want a science that upgrades a units armour, locomotor, animation, and weapon.

I have not seen it done in the sciences before.

You cant, you would need to make a science that lets you buy an upgrade that does all that stuff.

Or you could make it so you have a science that is a Super Weapon, when you use it, it drops a item on the ground that automatically grants a player upgrade.

Other than that, your on your own.

I thought thats what you said.

Id like to make it an upgrade you could purchase but dont know how to set the prerequists for an upgrade.

Not to be confused to build a differet unit. Such as getting the paladin, or the nuke cannon

The prerequisit for a upgrade is actually set on the command button
