How to unlock the Double KO achievement in Boulder Dash-XL - Definitive Guide
I unlocked this on level 4 with 13 enemies.
Just line up a rock that has 2 enemies below and push it down. Might take a few double kills before it registers. I got it on my third or fourth double kill.

This doesn't have to be done in arcade mode as the description states. I unlocked it while playing the second cave in retro mode
Basically what it says. Using a boulder, crush two monsters at one time. I was able to complete this on Level 18 of Arcade Mode. There is a spot on the right where one monster is moving left to right and another is up and down. Timing is the key here, but that was the first spot I had the best opportunity. There is another spot earlier on, however, when I tried it on the other level, I was not able to push the boulder over on to the monsters.
