Helmet System
One of the most exciting innovations in HND is that of the helmet system. When targeting another non-friended player or NPC that is wearing a helmet, all the player sees on their HUD is a targeting box that lists the target's race (through a symbol). The only way to find out who is underneath the helmet is to defeat the owner in Combat, for when they fall their helmet will roll from their head and their name and guild will be added to the targeting window.
This system allows for some anonymity, while still avoiding problems of killing one's own race.
