TOO LATE!
Well done, conscripts. The fortress is complete, it is planned to be fully operational before the day ends. When fully powered the fortress will easily be able to wipe out any pathetic counterattack our enemies attempt to create. This shall mark the first major victory in the war against the Shy Guy menace.
...Unfortunately, The mind control beacon is using the energy we will need to power the fortress. I'm afraid we have little choice but to deactivate it until we are able to produce the energy needed to power both structures. With the tower deactivated you will most likely return to your former lives. But fear not, you will be called to serve us again someday.
