LitLThomas modded an emote into halo 3 that I think encapsulates the kind of emotes I want in the game perfectly. Look him up on twitter to see it (because for some reason they thought it was a good idea to remove links from these posts smh)
I don’t want spartans doing trendy and cringey dances, but that doesn’t mean there can’t be a flare of comedy to it. Bungie had this fun humor in their games. So basically just think, “would sgt. johnson do this emote?”. If the answer is no, leave it out. Some emotes could also be “tactical”.
