So a possible game type that could happen as a limited time event or full fledged addition, is maybe a survival horde game type using the Hive as an enemy. It could maybe be progressive as well like having Thrall to begin with, and eventually mix in some cursed Thralls, then as it gets harder put in some hallowed and this can be applied to all hive enemies in the game. But what would be maybe nice would to be just have Thralls and its respective variants. Another addition could be bonus rounds (which could be XP+ along with maybe more items?) and maybe game-type specific weapons, but in the end all of this is optional. And maybe a cool thing to add is on a very high wave level maybe there is an end, and you can get cool sh*t and a cool cutscene. IDK, I think this sounds like a cool idea, and I would love to see it in Destiny. (UPDATE) Also a cool addition would to be maybe if you get enough points during a bonus round, or whatever reason, one round or YEAH WHATEVER, you could use the sword of Crota (I think that's what it's called). It's that sword you get on the mission on the moon, anyone know. I think that'd be an amazing addition.
