Spacebase Startopia

3rd mission Nightlife
Earned 25000 Energy, which can be done by
build a disco
build a arcade
build a starcat
build a blackhole
build a lootbox
build a recycle center, and garbage bots
minimum objective energy from each fun building is less then this, so if you are close to winning, maybe try deactivating what you still need and wait for your other buildings to get the energy
can get 25000 from just one source if you really want, but i dont recomend that
