I recently bought the game Super Meat Boy, and have noticed there are "bandages" spread out across the world. What do these bandages do? Is it a sort of "score-keeper", or does it have a practical use?
They unlock characters. You unlock one character after 10 bandages and then another for every 20 that you collect beyond that up to 90 and then 10 more gets you the final unlock. The precise characters gained will vary depending on whether you are playing the XBOX version or the PC version.
