After Ethan and Gideon are at the escape pods, Ethan will instruct 
you to find Olivia. You must first find and use six hidden buttons 
in this level. To find the first button, repeatedly hit the locker 
in the first room until it disappears. To find the second button, 
look behind the pillars to the left of where you start in the first 
room. To find the third button, exit the first room in the direction 
you entered this level. The button is located near the door with the 
fire in front of it. To find the fourth button, look behind the left 
locker in the second escape pod room. The fifth button is found behind 
the pillars in the second escape pod. The final button is located on a 
door on the first section of walkway overlooking the large room with 
people running below and ships flying in space above. Once the final 
button is pushed, simply turn around and follow the now open path to 
the secret tunnel. Once on the other side you can find a pipe that 
resembles those from the Super Mario Bros. Climb into it to warp to a 
Mario-style cave, where the music also changes to match that of a 
classic game. Jump across the platforms and reach the end of the cave. 
Once there you will find three more pipes. Each one of them will warp 
you ahead to a farther point in the game. The pipe on the left advances 
to the intermission sequence showing Marin, Giddeon, and Olivia taking 
off from the planet in Chapter 4. The middle pipe warps you to the top 
of a building in New Bahn. The pipe on the right warps you to the escape 
pod intermission sequence.
