Into The Ruins
Now that you have all that out of the way, it's time to finally head into the ruins here. Pull the block away from the door and open the gate leading inside. (As far as we can tell, there's no particular puzzle involved with the tilting ruins here...although we're probably wrong!)
Inside the ruins, smash any suspicious-looking stacks of blocks in your way; one contains a red orb chest. You'll eventually come to a large doorway and a path leading off to your left; the path ends in another red orb chest. Head back through the doorway and begin killing off the firebugs and wraiths that appear; focus on the firebugs first, jumping and grabbing them, or they'll pelt you with fireballs. When everything's dead, smash the rock in the middle of the cave to reveal a grapple point. This one will spin you around as long as you hold down the R1 button, so time your jump so that you move to the far ledge here.
After a couple more grappling point jumps, you'll come to another section of bog. Climb the ladder on your right and slide across the rope to reach a Gorgon Eye, then quickly dash across the tree stumps in the bog until you get underneath the soldiers that are firing explosive grenades at you. Smash the pillars here to drop the soldiers down, then grapple them to death. After the left and right pillars are destroyed, you can R1 to grab the central pillar and shake it with the L1 and R1 buttons; that will spawn a few more soldiers, but also give you the path up to the ledge above you. There's a red orb and green orb chests near the edge here, in the small alcoves.
Bodies In The Water
;)
After you drop down into the large circular room, you'll be confounded with a puzzle. You have to depress two switches to open the gate that leads on, but you only have one dead body. It would be possible to open the gate if you could put the body on the plate behind the half-opened grate, but you can't jump over it while carrying the body. Hmm...
The answer here lies in the water. If you flip the lever in the circular room, then smash out the rear walls to each of the small alcoves, you'll find a river that flows behind all of the rooms, which apparently goes in a circle. If you drop the body in the river that you have access to, then jump over the grate to the left room and wait in the water there, the body will eventually appear. Grab it from the water and place it on the left pressure plate, then jump over the grate and stand on the central plate. This will drop the northern grate long enough for you to roll across it.
River of Blood
You'll spot the Spartan warrior who was pleading for your help earlier at this point. You won't be able to reach him directly, so jump onto the gear in the water and latch onto the lever nearby to start moving it. You have to move it far enough along the chains so that you can jump to the next gear, but your progress will be impeded by undead soldiers that hop onto the platform as you move. You can quickly dispatch them either by grappling and throwing them overboard with the square button, or by hitting them with a couple of triangle-button attacks with your barbarian hammer.
;)
Navigate the gears until you reach the far exit from the river, where you'll encounter a stone golem which will bar your path. If you stand far away from it, it'll throw rocks at you; getting up close and personal will force it to whirl around with its fists. It's easiest to take it out with melee attacks. Get close enough to force it to whirl around and note the range of its fists during this attack. After it finishes the whirl and begins settling up, dart in with a combo, then dodge backwards as it begins a new one. As long as you're quick to dodge, you can repeat this action a dozen times or so to weaken the beast. When the O-prompt appears above its head, finish it off with button presses and break the tree behind it to move on.
When you reach the rope suspended across the area, start crawling along it and use the O button to grapple your enemies to their deaths. When you reach the end of the rope, drop down and open the shutter near the rotating wheel to reveal a fate statue; this will let you use your L1 and R1 buttons to freeze time and allow you to cross the wheel.
You have to navigate through a rolling platform here, replete with undead soldiers. There are petrifying beams that cover the hallway you need to move along, so don't jump. Use grapples and throwing attacks to clean out the soldiers as they pop up, but be aware that you get 15 extra orbs for killing a soldier while it's petrified. They won't cross the beams themselves, but if you knock the soldiers around a bit, some will turn to stone and let you pick up the bonus orbs for finishing them off in that manner. If you don't want to deal with them, just roll your way to the end of the path and use a special attack to destroy the wooden wall there, then use the grappling point to swing across to the platform nearby. Destroy the statues to reveal a wooden block and push it to head...
Right back to the teetering ruins you were at previously. Now that you have two sets of blocks, maybe you can do something about them? In order to use the block, jump onto the teetering building and push the old block back towards the left side of the screen, so that there's a small ramp leading onto the building. Then, push the new block onto the building from the ramp, ensuring that both of the blocks are on the portion of the building that leans. With that done, kick both of them over to the far side of the building, near the door you used earlier. This will cause the building to tilt more heavily than it previously did, allowing you to move to the edge of it and use the R1 button to throw the whole thing into the river below.
