when i was playin i hopped on the silo and it wasnt there i killed all my other teamates so that they wouldnt blow up the wraiths but there was only 1 wraith?!? it was on normal too
there are two..the other wraith is already destoid buy your helpers and there is one sitting up on the ramp.dont destoy the one down on the ground thats shotting at you.there should be three altogether.one destoyed one shotting,and one on the ramp.
well try to wait for the other wraith that comes near the door you have to enter. but if you have live, try legendary with a couple of friends. if you need help my gamertag is RtG C RuSS12
