Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "mydefuser.ini" file in the "\advent rising\system" directory. Scroll down to the area with unallocated letters. Try using "y" and "u" for this, as you will not accidentally hit them during combat, and they are together where you can reach them easily. For "y", enter "Blizzow 1" so the line appears as "y=Blizzow 1". Press Y during game play to have all of the powers and weapons at level 5, including jump and melee. For "u", enter "god", so the line appears as "u=god". Press it during game play for god mode. The message "God mode on" will confirm correct code entry, however your health will still decrease, but you will not die when it is all gone.

-After returning to the escape pod bay with Olivia, Ethan tells you to take Olivia and run to the escape pod while Olivia tells you to take Ethan. At this point, you may select either one depending on who you walk towards. If you walk towards Ethan, you take him to the pod and see Olivia get scanned. If you walk towards Olivia, you take her to the pod and see Ethan get scanned.

-At the end of the first chapter, you must select who gets to come with you on the escape pod. This choice only affects the banter between your character and the one you save. After the credits end, you will play the epilogue, and the person you left behind in the first chapter becomes the final boss of the game.

Wait until the credits end to fight another Boss in a bonus battle.

When fighting Ethan in the bonus battle (if you took Oliva), he will start charging the black ball above his head. Equip the Surge power. When he tosses it, you can knock it back. He will catch it and throw it back three more times. After the third time, it will hit him. He will then fall to the ground and three gold colored rocks will fall from the ceiling. Use Lift to pick them up and throw them. Repeat this about four or five times to kill him. You and Ethan will then get sucked into a warp hole and get dumped in a snowstorm. Your health will drop quickly. Walk to the top left and a strange figure will find you.

Shoot it in the head whenever it picks up a rock. It will drop the rock on its head and fall down. Once it falls down, continuously shoot it in the head. Do this three times and you will kill it.

For easy kills, max out your Aeon Pulse to level 5. After doing so, switch you Aeon Pulse so that you will be able to do radial flare. Since your pulse is maxed out, it usually kills in one hit. It will also mostly kill everyone in the room that you are in .

After Ethan and Gideon are at the escape pods, Ethan will tell you to find Olivia. You must first find and use six hidden buttons in this level. For the first button, repeatedly hit the locker in the first room until it disappears. For the second button, look behind the pillars to the left of where you start in the first room. For 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. For the fourth button, look behind the left locker in the second escape pod room. The fifth button is located 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 center 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.

Find and use the six hidden buttons in level B of this chapter. To find the first button, destroy the black object in the wall in front of you when you first start. After you pass under a large gun and you will walk into an open area with three more black objects. Destroy the black object in the corner opposite the entrance to the area to find the second button, then go up the small ramp and wait until two bridges appear, on one side of another large gun. Use a charged jump from the bridge to reach a platform above the large gun to access a hidden room with the third button. Continue through the level until reaching an area with three doors that enemies are appearing from. There should be two small doors to the right and a big door under a turret farther back (which leads to a tunnel that contains the fourth button). To find the fifth and sixth button, get to where you must use a switch to create a bridge. Do so and start crossing it. While walking across the bridge, look to the right to find an alcove with two big explosive objects in it. Destroy both of them to find the last two buttons. Note: Use the button closer to the start of the bridge first or the secret pipe will remain locked. After all six buttons are used in order, the locked door at the end of the bridge can be opened, leading to the secret Super Mario Bros. pipe.

When at an area with lava, turn on Time Damp mode and jump in the lava. You will die but do not release Time Damp until the screen goes black. When you return to the previous checkpoint, Time Damp will still be on but your energy bar will not decrease. Time Damp will stay on until you click Time Damp again or go to a video.
