XP levels

As you build structures, collect income, repair structures, and perform some other ingame actions, you gain XP points. At certain amounts of XP you will level up. You will also recieve a bonus for achieving the next XP level and will have the ability to purchase and build new structures. Check out the table below to find out when and what.

Note: On reaching Level 34, the game also gave me a message: "The new facilities will be available in the new versions." I believe this means that new buildings will be added in the future which will require XP Level 34 or higher to unlock!
