One of the easiest ways to get this achievement is by blowing yourself up with the Fuel Array. The Fuel Array is located on the back side of the Escape Pod (MUL-T, Acrid, and Void Fiend do not spawn with normal Escape Pods, thus cannot use this method in singleplayer). To get the Fuel Array, walk around the pod, press 
to open the hatch, and again to pick it up.
The Fuel Array detonates when the player drops below 50% health. Be aware that using a Shrine of Blood (or Void Cradle, etc.) will activate it instantly.
For more information about the Fuel Array, see the wiki.

- I would recommend doing this on Drizzle (easy) difficulty so you do not accidentally blow up before there are enough enemies. You select difficulty on the character select screen.
- After you have picked up the Fuel Array, just run around, avoiding damage, until you think enough enemies have spawned.
- Once there are 15+ enemies in the area, allow your HP to drop below 50%. This should blow you up and all of the nearby enemies. The explosion radius is pretty large, so you don't need to worry too much about enemies being too far away.
- If all goes well, the explosion should kill you and all of the enemies in the blast radius, and the acvhievement should pop.

This is one of those achievements that is likely to happen naturally without trying for it, and you may even wonder exactly how you did it. That's actually the case for me, since it unlocked without me doing anything conscious to unlock it. However, with the Artifact of Command from the roadmap, you can select exactly what items you want to make this achievement more likely to happen. You're going to obviously need something AoE, like an explosion. Some examples are below.
Razorwire (green) - you'll need six stacks of this to have it hit 15 enemies, but this is a pretty solid option when coupled with other damage buffs you have, since there's no aiming involved
Sentient Meat Hook (red) - this won't kill the enemies but it will pull them all together, making it easier to kill a large group all at once
Shatterspleen (yellow) - this is, by far, the best option, because the explosion from enemies dying is huge. Coupled with stacks of Lens Maker's Glasses, every enemy will explode, drastically improving the chances of tons of enemies dying at once
Missile Launcher (equipment) - it only shoots 12 missiles, but they are homing and they are guaranteed to hit enemies, so this is a great option
Preon Accumulator (equipment) - the blast radius is small but very powerful. The downside is that you need to aim it and it shoots slow. You'd have to get pretty lucky with this one
I should mention that, when I unlocked this achievement, I had none of the above. I was playing as the Huntress and had nothing to make enemies explode, so I was very surprised to unlock this. I think you'll find that, in later stages, enemies are in high enough quantity that, if you've made a strong enough build, you'll do this naturally.
