Halo: The Master Chief Collection

Fusion spirals are ground-based UNSC containers containing super-hot plasma. As you might expect, the contents of the container are extremely unstable and can cause harm if the container is destroyed. In the Lockdown map, many of these containers are located on the top floor of the middle platform. Start a custom game with a friend on this map and meet there. Using a weak weapon such as an SMG, destroy the enemy's shields and then have him stand next to the container. Shoot the container and it will kill your opponent and you will receive the achievement.
