A HA I found it!!!!
Just let a few lucky persons see. The Astericks are there to avoid having this topic searched.
Go to where the imperialist is in Alinos Gateway (As Spire)
Now, look at the island where Samus's ship would be in Single Player. Walk off the platform, and turn to the left. You should see a rock pillar. Walk towards it, and when you hit it (It's only a few steps), and turn to the left. You should see a small gap between the wall and pillar. In biped mode, walk in it all the way.
Now, switch to Dialanch and hold right. If done right, the pillar will dissapear and you'll be inside it.
Don't count your chickens before they hatch, however. It's still easy to headshot your ass while you're in this pillar.
