Special Delivery (achievement)

Special Delivery is a Halo 4 achievement added with the Crimson Map Pack. It is awarded when the player kills an enemy player with a melee attack while landing from a man cannon.

Trivia
Upon release, the achievement was glitched and would unlock seemingly at random. Numerous players reported being awarded the achievement for Kills from the Grave, melees and Flag Carrier Kills.

If unlocked as intended, the achievement can only be unlocked on Wreckage, as it is the only Crimson map with man cannons.
