How the heck do I get in the locked door? Can I even get in? It does not have one of those glowing things on it that other doors have where you can shoot something on the wall and they open. But I know there is fully rendered game world on the other side because I have seen it from a different area on the map. I just don't know why they would make that area inaccessible because it has some really cool design to it.
