Pour It On
Pour It On is an achievement in Halo: The Master Chief Collection. It is unlocked by beating the 40,000 point par score on the level NMPD HQ. The achievement is worth 10 gamerpoints. Though it can theoretically be unlocked on any difficulty, more points are awarded in campaign scoring when playing on higher difficulties.
Players can earn extra points by destroying unoccupied Shade turrets as the game does not differentiate between piloted and empty vehicles; Halo 3 and Halo 3: ODST are the only games in the Master Chief Collection with this campaign scoring quirk. That being said, the majority of the player's points will be earned by destroying Type-52 Phantoms at the end of the level.
The name of the achievement is taken from a line spoken by Buck near the end of the level: "Pour it on boys, we're almost through this!"
