Many players don’t realize this but beacon towers actually help in your scouting.
Have you ever wondered why your informatics level is high but sometimes you get bad scouting reports? The reason is because your beacon tower helps in scouting. Both your informatics and your beacon tower need to be equal to the level of the flat you are scouting. If you’re scouting a city it needs to be equal to the level of the walls of the city.
Don’t neglect your beacon tower! I love all the newbies with level 3 beacon towers that build up massive cities but never upgrade their beacon towers. They just don’t realize how important the beacon tower is!
