God of War III

Story Related Trophy. Cannot be Missed.

After you go through the portal in Aphrodite's chamber, you will be back in Hades. Speak to Hephaestus and he will tell you to go in to the Tartarus pit to get the Omhalos Stone.

In order to get in to the Tartarus pit, you need to open the Gates of Tisiphone. In order to do this, you first will have to defeat two Chimera enemies. Be very careful when taking these two enemies down. They will surround you and give you some heavy damage if you let them. The second Chimera will appear after you have brought the first one to its second form (when you sever the snake tail). Make sure that you leave all of the barrels until the second one has appeared. Lure them both towards one of the barrels and let a flame arrow go in to the barrel so it will explode on both of them. You'll want to pick one of the Chimera to focus on primarily. Dealing damage to both of them (other than what the barrels do) is not recommended because you'll lose track of which one has absorbed the most damage. Continue to hit one of the Chimera until it is dead and go to work on the other one. When it is dead, you can now figure out how to open the Gates.

This is where trying to explain what to do gets tricky, but here goes:

Step 1. Interact with the chains on either side of the doors. This will get a couple of blocks to come out of the wall. Interact with both of the blocks to push them back in the wall, revealing ledges and grab points.

Step 2. Climb up the blocks on the left side as far as you can (it will only be two blocks) and wait for the harpy to appear. Ride on the harpy all the way over to the right side block that is sticking out. Stand here for a second and wait for the blocks to come back out of the wall. The block will push you off the ledge, so jump up on top of that block and then jump up on top of the one above and beside it.

Step 3. You can now jump to the left on to the gold ledge in the middle. Jump from that ledge (in the middle) to the next ledge on the left (there will be a flashing point that you can interact with). Interact with the switch here to push that block in to the wall. This will make some more blocks on the right side come out and make a harpy lower down.

Step 4. Grab a ride on the harpy over to the right side where there is another interaction point. Interact here to push the block in to the wall.

Step 5. Jump back to the gold ledge in the middle and interact with the switch here which will open the Gates of Tisiphone.

The trophy will pop up during the animation of the Gates opening.
