Worms Don't Surf

Worms Don't Surf is an achievement in Halo 5: Guardians, awarded for knocking two Hunters into the ocean during the Battle of Sunaion.

Strategy
It is highly recommended to activate the Tough Luck skull for this achievement, as this will make the Hunters go berserk and perform their shield bash attack more often, which makes them more prone to falling into the ocean. If the player hasn't obtained the Tough Luck skull yet, they should consider obtaining it from the mission Guardians.
