So I did the black garden mission on Mars and before I go down into the maze like garden I go farther over and there's this huge opening where a huge force barrier is blocking it. Every time I get close to it, it bounces me back quite a distance. Behind it, it looks like a normal cave that could lead somewhere else in the mission. What is this? Why is it in the game? If you want a picture I don't have one yet. But you can look for yourself. After you kill the stuff in the area before the entrance into the maze garden below, there's a pathway beyond that . It in the corner to the right.
