To obtain the hidden Red Orb cache here, double jump when you are in front of the sign a few times and you will obtain them. Go further up the ramps and through the yellow door to reach the Endless Infernum. Go through the green door to return to an upper floor in the Chamber of Echoes. Defeat these along with some Hell Sloth, then jump onto the pipes that run over the bridge then up again into the alcove for a Blue Orb Fragment. Gluttonies telegraph their attack by taking a step back and drawing a breath before they fire a blast of sand. Here, the demons Hell Gluttony are introduced.

Torn flag in the upper right corner resembles rotated number "4", depicting mission's number. Destroy them for Red Orbs, then activate the elevator and get on to be transported to the Incandescent Space. In this room, the damage wheel is used to activate the elevator, but with some fake Damned Chessmen sitting on top of the platform. You can't obtain the item inside the cage just yet. Several others will appear around the room as you kill the first few take them out, then head through the door at the top of the room. You can try your new Devil Arm, Cerberus on these demons. If you prefer to take things up close, run toward them and up the stairs, then perform Helm Breakers to knock them down. You can stay in front of the doorway but be careful not to let the door grab you and simply fire Ebony & Ivory at them until they die if you want to be safe. There will be a short cutscene sequence with the appearance of several Enigmas.

Go through the door at the end to reach the Living Statue Room. Some Hell Prides are in this hallway but defeating them is optional. Jump through and wall-jump to reach the side of the ramp with the blue door enter it.

Move to Dante's right and up the stairs until you see where the floor is broken. Climb up as far as you can and collect all the Red Orbs. This mission begins at the entrance of the Chamber of Echoes.
