The Eye of God is the final area we recommend completing and the main section of Act III of Hell is Us, after taking care of all your unfinished business. Although you’re completely free to search for the Lymbic Forge Keystones in any order, several collectibles can be missed once certain events are set in motion. It’s therefore best to follow a specific order so you don’t ruin that coveted 100% completion.
Back at Lake Cynon, descend towards the Lymbic Forge, through the door beyond the mechanism used to lower the water level in the depths of the reservoir, and go through the door you opened using the four Lymbic Keystones.
Shortly after moving forward, you’ll be attacked by a large group of weaker enemies. Defeat them all and use the lever beside the gate at the far end to continue. It’ll take a while to make it all the way through the tunnel. Eventually, you’ll see a save point, a left turn and five glowing spots.
Approach the glowing spots to collect the Orb – Cobalt, Orb – Gold, Orb – Emerald, Orb – Crimson and an Amine Prism – Rho, along with the Scroll – Failsafe. Go through the tunnel that opens to reach the warehouse from Raiders of the Lost Ark, obviously. This area is home to a large number of creatures, so remember to eliminate them all to clear it.
Among these monsters are several unusually large Lymbic creatures that serve as the area’s Guardians. Don’t worry, you’ll run into them while exploring. Your objective is to defeat the Guardians and place the four Orbs at the feet of four specific statues out of the eight found along the northern and southern walls.
On the northern wall, you need the second and third statues from the left. Place the Orb – Crimson at the second statue and the Orb – Cobalt at the third.
On the southern wall, you need the first and third statues. Place the Orb – Gold at the first statue and the Orb – Emerald at the third.
You’ll need to make your way between the crates and tents. Don’t worry, it’s easier to find the way yourself than waste time reading a lengthy explanation, especially since there’s nothing here other than enemies and consumables for now. Once you reach the Timeloop area at the far end, head to the southern side. You’ll find some desks and a filing cabinet containing the Baseball Cap – Gilded, the final baseball cap.
Once you’ve defeated all four Guardians and placed the four Orbs at the indicated statues, you’ll see four blue beams of light shooting towards the Timeloop.
Approach the Timeloop and close it using the Amine Prism – Rho you collected earlier. Afterwards, all you need to do is place the Heirloom Necklace on the pedestal to finish the game. You may still have some enemies left to eliminate at Lake Cynon before the area is completely clear, but you can take care of them after finishing the game, so don’t worry... everything else will already be done.
