How to Use the Urns for a Bonus Play in God of War 2

Look for the "Urn of Gaia" in the Colossus level near the first block puzzle you encounter. Push the block into the room with doors on every side of you and push the block into the right-side passage. Continue pushing the block through the right-side passage all the way to the end and then climb the block to reach a hidden crevice with two chests and the "Urn of Gaia."

Find the "Urn of the Gorgons" by using the "Golden Fleece" on the freezing jets. Accessing the area will require you to backtrack to the area with the conveyer belt once you first acquire the "Golden Fleece."

Find the "Urn of Olympus" in the area where you first get the spear. Once you have acquired the spear, push the "Fate Statue" into the circle and rotate the statue to face the door exiting the area. Now, push the statue to the edge of the pool of water and then dive in and swim to the other side of the pool. The moment you climb out of the water, use your ability to slow down time. Move across the gap and then run as quickly as you can into the small cave with the rising gate. You will find a chest containing the "Urn of Olympus."

Find the "Urn of Prometheus" in the Atlas stage when you are traveling through the lava cave. When you are climbing along the cave ceiling, notice the two stalagmites. Break the second stalagmite by attacking it to reveal a hole in the ceiling. Climb through the hole to find the "Urn of Prometheus."

Find the "Urn of the Fates" by achieving the overall rank of "Mortal" or greater in the "Challenge of the Titans" game mode. "Mortal" is the lowest rank you can achieve, so all you need to do is complete all seven challenges of the game mode to acquire the "Urn of Fates."

Find the "Urn of Poseidon" by achieving the overall rank of "Spartan" or greater in the "Challenge of the Titans" game mode. "Spartan" is the third highest rank (next to "God" and "Titan"). You can achieve a higher rank than mortal in each challenge by not getting hit (or at least not taking too much damage), getting a high combo score, killing as many enemies as possible, and finishing the current objective as quickly as possible.
