    You can get this by playing starting with the Ravenholm chapter. You can only use the gravity gun, but like the name suggests, you can use one of the many saw blades lying around to chop up the zombies as they attack you. You just can't use another weapon besides the gravity gun. (Other objects that you pick up and shoot with the GG are fine, too... so is using fire.)

    One thing to note... the achievement doesn't unlock until after you've left the graveyard, gone down the shaft, through the water, up the mine, and gone into the light. In other words, you need to be at the next chapter (which would seem to be obvious), which isn't until a bit after you leave Ravenholm proper.

    I only say that because I freaked out a bit until I finally got it, wondering if I'd just wasted the last hour. :-p

    RadiantViperGetting 1 or two negative votes while having 10+ positive tends to be a sign that your solution is even more awesome. Seriously, almost every one of my 20+, 30+ positive solutions has a single negative attached to it x.x

    Mental Knight 5This is a very nice (and important) detail that for some reason is lacking in other guides. So it totally gets a positive vote from me. If I had to guess why anyone didn't like it, well... it's not a full guide complete with advice. It's just a note.

    For this achievement you can ONLY USE THE GRAVITY GUN, you can switch to other weapons, but if you hit the trigger then you can't get the achievement.

    There are many saw blades scattered throughout interiors of the buildings, try and keep one with you at all times as they can take out the zombies in one hit. All in all this achievement isn't to difficult, just be aware of where zombies are and try and keep some kind of sharp instrument close at hand to hurl at them, if not use anything and everything you can.

    Also when you get towards the end where you wait for the container that the priest sends towards you so you can get across. At this point the leaping zombies will climb up the pipes to get you, simply run around in circles and they will keep chasing you (not being able to hurt you) until the platform gets to where you are, jump on and you only have one more area to get through after that, which mainly consists of regular zombies and some head crabs.

    DragoKhanI had some problems with the mine at the end, to many headcrabs, but found you can crawl almost to the end of the tunnel on the wooden beams, where you have to jump down. I did it without killing any of the crabs.

    darkavenger786I've fired off my .44 Magum once but not at any zombies, will i still get the achievement or will I have to restart the level?

    Crimson DrifterPretty sure you have to restart, if you hit the trigger with any other weapon out, regardless of where you are aiming will void the achievement.

    The way I did this is to carry Dog's ball, the deactivated roller mine, to Ravenholm with me. Using the roller mine is a great way to get through this level because it will roll towards zombies and they will attack it instead, distracting them while you find something to kill them with. Also it kills headcrabs when it rolls over them. Doing ravenholm this way is a tone of fun because you can watch loads of zombies swarm and try to kill the roller mine while you watch from a good vantage point. Just don't set off any explosions close to the roller mine or you can wave goodbye to your little friend.

    SashamorningReading your last sentence made me think of what I had to do to my Weighted Companion Cube in Portal.

    I'll still never forgive myself.

    HeyMrSpacemanI used this method, brilliant for most of the level, but wasn't able to take Dog's ball with me across to the church, it disappeared in the journey across. But the church graveyard has lots of blades and fuel drums to use instead.
