At certain points in the game, a variety of upgrades become available to your existing units. Unfortunately this produces a really tedious management issue, where the user has to select each individual unit and click on each type of upgrade. Some people mentioned that you can upgrade multiple units at a time, but either it doesn't work or they have to be the same unit.
Is there a hotkey or shortcut for quickly applying upgrades to units?
Best Answer
You can upgrade them all by clicking on your army, of course, and then select all units with
ctrl + Aand after that hover over any unit, theupgrade or disbandtooltip will appear, and select upgrade, like you were doing when upgrading a unit. It will even show the total amount for upgrading all units.
