My next amazing (or something like that...right?) creation. Pictured here are "Kills" achievements -- that is to say, you have to kill X amount of a certain unit to get the achievement. There are also different levels for each unit: first you may have to kill 20, then 50, then 100, so on and so on. (What tier you are on is displayed on the little progress bar on the right). For those of you that are wondering, you can definitely cheat this system. It's meant to be a challenge available to the player if they want it.
