KotCT has 85 separate missions that unlock gold, pops or equipment. Many of these are inactive until you complete the mission prior. We've now hooked up our mission system to Steam Achievements so you can show off your progress to your friends and enemies.
We've built icons for about 15% of the missions from easy to hard and dropped them into the BETA branch. So feel free to test them out there. (You will need to reset your progress to see any mission you already completed.)
If this works, we'll probably add a total of 25 hand-selected achievements for the steam version of the game.
Enjoy!
