Hit an enemy with a weapon bounced against a wall
Throw a brick (or other blunt throwable) at a wall so it ricochets off and kills an enemy. Put a wall between you and a target and lob the brick at the wall at an angle so the bounce catches them. Fiddly, but any level with a loose brick and a nearby wall works - just retry until the bounce lands.
