Better With Age

Better With Age is an achievement in Halo: The Master Chief Collection. It is unlocked by beating the par scores on all Halo 3 campaign levels. The achievement is worth 20 Gamerscore. Though it can theoretically be unlocked on any difficulty, more points are awarded in campaign scoring when playing on higher difficulties.

Trivia
The name of the achievement is a reference to the phrase, "Like a fine wine, (I/thing) only get(s) better with age," and is a suggestion that Halo 3 shares this quality. The achievement Like a Fine Wine covers the first half of the saying.
