Doesn't need to be complex, just some generic lines like: * "Reloading" * "Throwing grenade" * "Smacking that Dreg (or any other wordchoice)" * "Time for action" (when casting super) People don't use the game voice chat, sadly. Would be nice to have something like that for all the players that don't use voice chats or play solo all the time. It adds to immersion. It can be made optional dialogue (like in Halo 4-5 and Infinite). And it doesn't need to be for each race a different voice actor. Just 1 male and 1 female. They don't speak our character, they speak the players that play with us... And we can't see what race they are, nor does it matter.
