Super Meat Boy

There are 20 bandages in each chapter of the game. They are located in both the light and dark versions of the levels as well as in levels located inside warp zones. The dark version of each level is unlocked by beating the par time of the light version. You'll need to grab each bandage and successfully complete the level for each bandage to be considered as collected. If the bandage is in a warp zone, you'll have to complete all 3 levels of the warp zone in order to collect it.

Here are the locations for the first 20 bandages in the game, all found in chapter 1, The Forest. Most of them are extremely easy to get!

Light Version:
1-4: Nutshell
1-5: Holy Mountain, in levels 1-1 and 1-2 of the warp zone, "Sky Pup"
1-7: Diverge
1-9: Safety Third
1-11: Fired
1-13: Tommy's Cabin
1-18: Altamont
1-19: Intermission, in levels 1-2 and 1-3 of the warp zone, "Hand Held Hack"
1-20: The Test

Dark Version:
1-3X: BZZZZZ
1-5X: Creamsoda
1-10X: Walls
1-13x: Tommy's Condo, in levels 1-2 and 1-3 of the warp zone, "Space Boy"
1-14X: Mystery Spot
1-15X: Kick Machine
1-17X: The Clock
1-19X: The Queener

Once you collect 10 you'll unlock the achievement and unlock Gish as a playable character!

If you are almost done with the game (or not, either way) there is a glitch where you can gain unlimited bandages to obtain the achievements.

first go to any warp zone and beat the first level, after that die till it puts you back to the map...now go to any level that has a easy band-aid (that you haven't got yet!) and grab it and then finish the level...it will count as how many bandages you have but not show on the map...you can then rinse and repeat till you have your achievements.

***it will not save any of the bandages once you exit out...

The publishers/developers DO know about this and it will be patched shortly...but for those having trouble getting bandages this is a great way to go about it!
