de Blob 2

You earn Gold Liberation awards by freeing/painting the citizens of the levels. Some are out in the open while others will only come out once you completely paint a series of buildings. Some only come out while you are doing the challenges per each level. If you do all the main objectives and then complete the challenges, these will appear as little brown guys on your compass (unless you missed some in a hole). This makes it easy to track down the ones you are missing. You can check your progress from the pause menu.
