I wish there would be a way to track these achievements a little easier. A lot of games have achievement systems that let you track your progress on individual achievements, like the Left 4 Dead achievement system.



For example, there's an achievement called "Mutant Overlord" which you get for playing 6 mutations. If you go into the achievement from the achievements menu, you can click on "Mutant Overlord" and a big list of all of the different mutations will come down. Each different mutation that counts towards the achievement, that you have played, will have a checkmark next to it to let you know you've already done that, and the others will have X's next to them.



Maybe it wouldn't be too hard to implement a system like this in the future for the achievements that require other achievements to be unlocked?
