How to unlock the Vacuum Cleaner achievement in Dead Space 2 - Definitive Guide
Chapter 1 - This one is mandatory. It's the tutorial on how to shut the decompression off, and you get one kill for free.
Chapter 3 - Right at the beginning you get your first area you can decompress stuff. You get attacked by one of those bombing guys(With the orange exploding sack on their left arm), two children, and one normal Necromorph. Ignore these four. Kill them but do not hit the glass in back. Then, run up to the glass and you should be attacked by five kids. Kite them all until you can see all five of them in front of you(You should go back to the entrance of Chapter 3, the elevator) and then shoot the glass. You get five kills here for a total of six overall.
Chapter 4 - In the Unitologist Indoctrination room, right after you fix the fuses to allow you to enter the other room, you get attacked by three Necromorphs one you leave the fuse room, so once the three pop out, destroy the window in front of you and now you have a total of nine overall.
Chapter 7 - This is the area with the rogue AI. I can't remember where it is, but once you enter the center of the room you get barricaded in by two Detonator Mines and some explosive barrels at the end of those mines, so you are unable to move them. You can move the explosive barrels at the end prior to the mines being triggered though, then you can shoot out the window yourself and get about 6 kills from all the explosive babies.
Chapter 9 - This is the last one. After you kill the Divider and proceed into the next room, there should be a Power Node on the right. Go to that and you will have a Black Necromorph drop on you and an exploder on the right walking toward you. Shoot out the window directly in front of you.

Round: 19 Necromorphs can be decompressed
Additional Information: The number of Necromorphs that can be decompressed is identical, regardless to number of Round or Difficulty Setting. Achievement progression can only be continued by playing New Game+.
Decompression windows appear throughout the game. They typically have white and yellow writing on the glass advising of future expansion and to take warning. Unfortunately there aren't enough decompression windows in the game to get this on your first playthrough, so you will have to finish it on a New Game +. The location of all the decompression windows are as follows:
-
Chapter 1: Upon entering the 'Critical Needs Room' a gas tank explodes causing the window to break. This is the tutorial for decompression windows. Shoot the red triangle at the top of the window to close the emergency gate. You will get 1/20 here.
-
Chapter 3: After taking the elevator from the 'Concourse' where the Lightspeed Boy Statue is up to the Unitology Lobby, you will see this window at the end of the hallway. You will be attacked by four necromorphs (Exploder, Slasher and 2 Pack). You can use the Javelin Gun here to get "Skewered In Space" and raise your count to 5/20 or you can lure them away from the window and kill them. Run up to the glass and you will be attacked by 5 Pack kids. String them along until you can see all five and head back to the elevator before breaking the glass. Using this method will net you an extra body for 6/20.
-
Chapter 4: In the Unitologist Indoctrination room, after fixing the fuses to gain access to the room on the other side, you get will get attacked by three Necromorphs upon exiting the fuse room. Break the glass for a total of 9/20.
-
Chapter 7: Upon entering this large room, you will be attacked by a Legless Slasher. You will also see the 'Power Grid Room' at the opposite end. Remove the explosive canisters from near the window and head to the middle of the room and yellow detonator beams will activate on both sides of you. If you wait until all the Crawlers enter the room, you can get your count up to 15. If you don't move the barrels you will most likely only get credit for two. Your new count should be anywhere from 11-15/20.
-
Chapter 9: After exiting the 'Pressurization Control 2' room, you will encounter a Divider. Kill it and take the elevator upstairs. Upon exiting the elevator, run quickly to the power node box to the right. Two necromorphs will drop into the room. Shoot out the window and quickly hit the red triangle because there is not much space to work with in this room. Your count should be anywhere from 13-17/20.
(Credit for the locations of each window goes to soliunasm)
Missable! You are going to need a minimum of 2 playthroughs (and NG+ to carryover stats) as there are very limited opportunities for this. On Chapters 3, 4 and 7 you will find large rectangular windows with inscriptions "Future Expansion" on them and yellow-black hazard bar on top (see Skewered in Space video for impression). Be very careful around them. When there are enemies around, shoot this window to break the glass and suck enemies into space. You will have to shoot the red triangle above the window to prevent yourself from following suit, or you'll die and the kills won't count.
On Chapter 7 use the following strategy from B0SS Zombie to obtain more kills:
You can track your progress by pressing and checking the "Trophies" option, this stat displayed is tied to your current save file. Your progress will carry forward to the next playthough only if you choose to play on New Game+.
Chapter 1 - 1 (on the first broken window).
Chapter 3 - 4 (if you throw out the first wave) and 5 if you throw out the second wave (kids)).
Chapter 4 - 3
Chapter 7 - 7 (you need to run into the doorway opposite. And don’t spare stasis on the necromoths. Delay breaking the window as long as possible so that the last child has time to crawl out from around the corner of the elevator). Don't forget to move the explosive containers away from the window, otherwise only 1 necromorph will fly out.
Chapter 9 - 2
To get the trophy (get 20 on the counter), start a new game+. It is possible at a different difficulty level.
