Hi all who were stuck at the lost sector puzzle step of xenophage. I did some digging and was finally able to easily progress all the puzzles and obtain the missing fragments. 1. Use a pulse rifle : I used messenger* 2. The puzzle codes will only work if the puzzle is the same as the start. Example: I watched Datto's video for xenophage https://www.youtube.com/watch?v=1EGPjPkuE3k Before he starts shooting, he shows the start of the puzzle. Pause. Double check that YOUR start is the same. If it is not. Leave and redo lost sector. Other tips: 1. Write down codes as it seems to be slightly timing based. (example: If you do not do the next code right after the stones change, it usually makes the stones not work. 2. If you mess up a code. You can reset by redoing the lost sector. (it is a pain, but you can still progress even if you mess it up once) 3. Learn the code by heart. Find which guide's codes work best! I struggled with the notion of double center. So Datto's middle callout worked best for me. Lastly DONT give up if it doesn't work the first try. Light's lost sector, I was so mad because it wasn't giving me a chest. I ended up just randomly shooting between the stones.. it gave me the chest. This is buggy!!** But if you really need xenophage for this season, I recommend these tips as it helped me get through the hell that is this step. *Notice sorrows lost sector is SO glitched. Enemies magically spawn under you and it's not fun. I recommend taking some serious adclear weapons into that one. Saves a ton of time for redos!
