Trivia

 * The achievement's title is a reference to Marvel Comics' Hulk, who is famous for screaming "Hulk smash!" when enraged or preparing to attack his foes.
 * In the Prima Official Guide, the achievement is titled "Whack A Mole" and the description reads "In Mission 9, kill 5 Crawlers with one hit of the gravity hammer". The Halo Waypoint web and mobile app also incorrectly lists the achievement as "Whack A Mole", but provides the correct description.
