Description: Shortly into the game's story, Shaxx will be available to speak with at The Farm. This will begin a questline that asks you to participate in the Crucible. First, do two quickplay matches. Second, do two competitive matches. Third, earn "glory" in any Crucible game mode. Glory is calculated by how well you play. After an update a few weeks after the game's launch, it appears one kill is two percentage, while objectives and wining matches may contribute as well. There's a bit of ambiguity, but essentially just kill people and try to win, you'll be done in no time. I got it done in four matches. After those three easy tasks, speak with Shaxx and the achievement will unlock.
