Hey guys this is some kind of aid to anyone with problems with the Petra-Variks quest line for Boolean Gemini (exotic scout rifle). 1. Complete the Taken War quest line 2. Complete Wolves of Mars Quest line 3. Wait for daily reset (not sure if this one is for everyone, but I had to do this to get to step 4) 4. Acquire and Complete Lost and Found quest line (You should get the rifle here, but if not move on to steps 5/6) 5. Go to abandoned quests (by Vanguard at tower) 6. Get the House of Wolves questline and complete it 7. Get to queen's wrath AT LEAST rank 3 These are the steps I followed and I got the rifle. This may not fix everyone's problems. But I can confirm I have it (On my main Titan) and this is EXACTLY what I did. Hope this helps guys. Edit: For step 3, there have been inklings of people just hard resetting their Xbox (shut down everything) and booting Destiny up again to go on to step 4. But I personally cannot confirm this one.
