Occasionally, the enticing clang of an opening loot box presents you with an Emote. An emote is a physical action that can be activated within the match, and is generally used to either instill excitement in your team, or elicit anger from an enemy you've just triumphantly eliminated. Or, more likely, you'll do it to simply get a laugh. There are multiple emote variations per character, and only one can be equipped at a time. To unlock them, you will simply have to grind until you're lucky enough to acquire one through randomized distribution.
