Signs and Xenospheres

Finding the signs:
- One of the most efficient strategies for finding a sign is to fly outside of the galaxy. Once you do so, you'll notice a blinking light with an arrow pointing to it. This is Earth. There will be another blinking light with a higher pitch sound than the one on earth. Follow this and it will take you to a sign. For all the signs past #2 you may want to back quite far out of the galaxy to locate them, I seem to get the best results by backing out and spinning the camera in random directions until I hear the high-pitch sound, then honing in on its location.

Using a sign:
- Using signs are pretty easy. Once you find the obelisk, there will be a beam of light coming from it, you'll want to stand in front of this light. This will pull you into a prerecorded message which will loop until you move away from it.
To retrieve the Xenosphere and find the next sign, use the Gigaton Laser/Heat Ray to destroy the obelisk (while listening to its message). From here you back out of the solar system (back out of the galaxy to easily locate the signs past #2) and repeat this process until you have retrieved all the Xenospheres.

Notes:
- You can retrieve the Xenospheres in any order you want provided you either have the Gigaton Laser or Heat Ray unlocked (to destroy the signs) and (if you are running the "All Xenospheres" Category) they are retrieved before the start of Mission 9, as when M9 is completed is resets you to a save state before the mission was completed, therefore you no longer possess that missions Xenosphere and you would be required to complete it again.
