I think their trying to make the Hive the scare factor for Destiny... Zombie-esk type creatures who (If the video is correct) few of them can wield weaponry... Hoards of Hive creatures running as you all screeching and crying out as you blast through them fighting for your survival... it's more thriller the horror but it will get your blood pumping... but wait, you just used every last bit of your ammo... now you have to either run for your life for die as you're over run by the Hoard of the Hive... Now you're heart is definitely racing... I've had few moments like that with video games...
