Zoo Tycoon

This achievement requires that you hire a staff member and upgrade them to level 3. There are three types of staff in the game: janitors, breeding specialists, and zoo keepers. Janitor is the cheapest to research and hire when starting a zoo. You will first need to build a janitor's office, found under Facilities. Once the office is built, go to Edit Facility>Staff>Hire. Here you can select someone to hire. Make sure to hire someone that is not already level 3 (the number of stars is their level). Once they are hired, select their name and then Upgrade. If you hired a level 1, you will need to upgrade twice. If you hired a level 2, you will only need to upgrade once. There is no Fame Rating requirement for upgrading staff and this can be done in any game mode.
