I've now played this level 7 times in a row (and at least twice before that) trying for this objective. With no way to know what each enemy names are, I just blew the hell out of everything for several rounds - no luck. I next thought it must be the quick little reddish orange guys - it took me at least 4 levels just to kill one with C4 since they die to a single bullet, and I guess that wasn't the solution. Anyone have any idea what has to be killed with C4 for this to count? I've used it on every basic enemy, the bigger ones, and I think the boss as well.
