How to unlock the Step on the Gas achievement in Call of Duty: Black Ops 4 - Definitive Guide
For all the achievements in Call of Duty: Black Ops 4 Zombies, besides the ones relating to the quests, you can use casual mode, but cannot use mutations.
This one I heavily recommend playing on casual with 3 bots. I was able to unlock this at round 35. Casual makes it much easier, and the bots with take some zombies with them making you less swarmed. For the packed weapon I recommend the ICR, because it is right on the wall in your training area. Pack it once, then repack it 4 times to get the full benefit of Pack a Punch. You do not want Brain Rot as your AAT, this will make zombies kill each other, and it wont count!
I would heavily recommend these perks, in this order: Stronghold, Dying Wish, Electric Burst, and Stamin-up.
The general strategy is to train in the War Room, and get a pretty long train going. Once the area is clear of any dogs, find a Nova 6 Crawler, shoot him, then immediately run towards him to get gassed. You will know if you are gassed, it will sound like a flash bang, and act like an old concussion grenade, making your movements extremely slow. Take aim and unload. Do this a couple times to get the 50 kills.
Right now it seems glitchy, not counting certain kills, or sometimes not exploding, but if you keep at it, you should get it.

I had this done by round 15 by running around the lab

I also don't believe that it has to be 50 zombies at once. It can be cumulative, so there's no need to risk getting overwhelmed by a massive train of zombies.

When you shoot a Nova 6 Crawler and they explode, some gas will linger, which will temporarily stun you. The easiest way to get this achievement is to train as many zombies as possible in the War Room, with at least one of them being a Nova Crawler. Once you’re ready, shoot the crawler, allow it to stun you and spray into the group you created. If you have your special weapon, this will make the kills even easier. You won't be able to get all of them in the duration of one stun but keep at it using this method and it’ll unlock eventually.

When killing crawlers with a knife, they do not explode. When killed with a weapon, they explode and release gas. You need to enter it, after which there will be some clouding and slowdown in the aiming movement. And in this state you need to fill the required number of zombies.
