This location is only accessible during certain plot points
You'll enter this area during another Laguna dream sequence. There isn't much to find here now, but your actions here have important consequences later on when you reach Lunatic Pandora. In particular, you can get a Power Generator later here if you're thorough, and they're quite a pain to get otherwise. The necessary actions are pointed out in the Items of Interest list, but here's a summary:
• You'll find three panels on the floor, and you can (and should) mess with the lever on the central panel
• Once the middle panel collapses, go right back to the panel room and walk on the right panel to mess with it as well
• Circle around afterwards and mess with the left platform as well
• Search the ground in the hall in the main entrance to find an old key (which Laguna promptly loses)
• Search the ground in the intersection from the other other entrance to find another old key Laguna loses
• You'll find two detonator switches—you should hit the red switch first, then the blue switch, after messing with all three panels
• There's a boulder you can push beyond the detonator
In addition to giving you Items later, these actions take out various soldiers within the site. The more you take out, the less you'll need to fight during the final battle in this area. The worst case is a series of five battles:
• Esthar Soldier (Human)
• Esthar Soldier (Human) & Esthar Soldier (Cyborg)
• Esthar Soldier (Human)
• Esthar Soldier (Human) & Esthar Soldier (Cyborg)
• 2x Esthar Soldier (Cyborg)
