The descriptions are all wrong, you have to make a combo of 20 enemies (you'll see the combo up and left of the screen). Just do the Boss Rush and keep killing the first type of enemies.

Actually, if you haven't already got this achievement, it is MUCH easier to hit the boss once, then wait for the weird sperm enemies to arrive, after the boss spreads his dots everywhere, he only spawns the sperm enemies, which can't shoot, so there is nothing to dodge :)

i found it easier to do this in endless lol
