Go to earth and do the first firewall mission. Retrieve the curious transceiver and enter the 4 codes First code -U D U U D D D U D Second code -U D U U D D U U Third code -U D D D U D D D U U Fourth code -U D U D U D U U After entering the 4 codes it will unlock another mission on earth. (Solo only mission, timed) Skip the beginning adds and go straight to the top grab the box. This will summon 3 hallowed wizards. kill the hallowed wizards. Will give the ikelos fusion core. There are 5 steps to the core. 1st - the archive mission on venus. (Any difficulty) 2nd - dismantle a legendary or exotic heavy weapon 3rd - Warsat on earth 4th - Warsat on moon 5th - Warsat on mars. Final step is to turn into banshee-44 and the quest will go cold. Hope this helps and good luck guardians. Edit: just got the quest "the sleeper stirs" from banshee-44 which starts off as you go do a special Saber strike at recommended light 280. I'll post more as I know Edit 2: after completing the strike you get the sleeper stimulant frame. Turn the frame into banshee for the sleeper simulant
