Alternate Entry to the Red Room on Artus Prime (Spoiler)
As an alternate means of entry to the Red Room on Artus Prime one can wait at the main door while the "process" inside performs (where the red light flashes and death is inevitable for all inside).
As soon as that ends, run into the room and jump ONTO the opening where the mining car is leaving (easier to do in 3rd person mode). Stand on the ledge outside, let the doors close (with you outside on the ledge) and wait for the next mining car to enter.
When that car is leaving, stand in the middle of the ledge, and jump. You should with enough patience be able to jump directly onto the mining car.
