Playstation Quick Guide
You begin in a quick simulation (the "-1" run). Nothing you do here matters.
After the simulation, follow Eliza through the illusory wall on BF15 and listen to her request.
Reach BF16 and find the impaled Archangel. Press forward into the Sense Sphere he's impaled on in order to reach the Bottom Layer. Once there, go straight and press forward into God.
Back in the Outer World, Neck Thing has become buried in the ground. Kill him (or give him heart seeds to do some gardening for a few cycles). Take Neck Thing's crystal and give it to the Sentry Angel. Then die or complete a dungeon to advance the plot
You can now enter the door that the Sentry Angel was guarding. Enter and kill what you find inside. Take the crystal.
Enter the Nerve Tower and follow Eliza through the illusory wall on BF2 (or BF15) and give her the crystal. The rest of the game can now be beaten in a single run of the Tower (but it doesn't have to be). Don't use the Angelic Rifle on this run.
Talk to the Guardian Angel on BF13 and watch her cutscene.
Find Eliza on BF15 again. Listen to her and watch the cutscene.
Enter the barred gate on BF20. If you've used the Angelic Rifle this run, the Littles won't let you in. Kill what you find inside. Get the crystal.
Find Alice on BF22 and give her the crystal.
Get to BF31 and enter the Bottom Layer as you did before. Merge with God and watch the ending.
