How to unlock the Chief, Smash! achievement in Halo 4 - Definitive Guide
Move through the next Portal where you'll see a Promethean Knight awaiting your arrival. Take him out first and then prepare yourself for a Gravity Hammer smashing Crawler triple kill. Purposely move into at least three Crawlers in order to make them swarm and try to bite you. With the right timing, take a swing with your Gravity Hammer and successfully wipe out three Crawlers at once.
Doing this correctly will instantly unlock your 'Chief, Smash!' achievement!
Please note - There have been reports of this achievement being a bit glitchy for some and not unlocking. It doesn't seem to be a major glitch so if the achieve' doesn't unlock on your first attempt, reload the last save and give it another go.
right, so as you teleporter hopping, make sure you pick up the hammer from the room full of weapons, you'll know it when you get there, and carry it through.
You'll get to a point where you have to make a stand and hold off a certain point where Cortana is doing something in the system, as soon as you get the order to stand ground, run towards where the crawlers are coming from, you'll meet three of them about halfway between their spawn and your point to gaurd, they'll instantly crowd you, swing and boom, Chief smash!
for the record, i was on normal difficulty, and i waited until my shields were jsut about down to make sure the crawlers were close enough, any harder and i think you'll die too quickly for this method to be effective
1. Choose level: Midnight - bravo
2. Apply skull: Cowbell (fact: increases GravHammer radius and maybe also power)
3. Difficulty: Easy (crawlers die easier)
You need to travel some time through the level. Crawlers can be further weakend by lesser weapons and maybe some armor abilities. on your way there are suppressors and auto-sentries, but I didn't bother with these.
When you get to the Gravity Hammer-teleporter-room, also pick up, for example the Incineration Cannon take care of the knights fast. This isn't however necessary. Wait for the checkpoint and portal opening.
Now rinse and repeat: Step through, run and backstab the knight and maybe shoot the lower knight with cannon. Then concider the crawlers, they're always all over you and in the wrong place. I got the cheevo in an umpteenth run, first killing the two knights and then running to lowest level where there happend to be a bunch of crawies so close to eachother that I could see them all at a single glance. I hit the middle one and there it was.
Note on failure: This is a useful spot because it saves before the portal and after failed attempt you can return there with start-menu and ponder on other secondary weapon choices and the crawler spots are somewhat random after few seconds in, so you will need multiple tries.

Campaign Mission 8 'Midnight' specific. Online not required. Can be obtained on Easy+.
Use 'Mission Select' after initial Campaign playthrough if missed.
The gravity hammer looks like this:
The Hammer is acquired in an armoury room shortly after Rally Point Bravo. Crawlers are the dog looking beasts with yellow-orange flame faces. The trick is to wait until many try to attack you at once, and kill 3 with one swing of the Gravity Hammer.
Right after going through the teleport, you can catch 3+ crawlers near each other if you're fast enough. Otherwise, just take your time, and get to the part of the level where Cortana will ask you to "defend". At this point, let the crawlers come to you, and you shouldn't have a problem finding them in a group of 3 or more.
Glitchy: Can be glitchy.
The Fix: Just keep at it until it unlocks.
