Mount Olympus

Shimmy across the vines and mosey on over to the chest. Poseidon's progeny is persistent; Gaia is bogged down a bit, but Kratos has some trouble of his own. The archers ahead can be quite irksome, but can be defeated with a single magic attack. Climb the ladder up to encounter more enemies, as well as a chest containing green Orbs. Just above is a grapple point, which can be reached by climbing atop the adjacent ledge and press R1 to secure the grapple. Hold the button down for momentum and swing across to the opposite ledge.

Here Kratos must utilize his incredible strength and climbing prowess to scale the mountainside to reach the top. The Leviathan proves to be much more of a nuisance for Gaia than ever before, but there's nothing to be done for her at the moment. Although you ultimately want to glide across the gap using Icarus Wings, there's a red Orb chest to be pillaged in the area just below. Replenish the health and magic meters before continuing on to the door ahead.

Tomb of Ares

Kratos comes to a big, empty room with only silence pervading the air. Looks like a bad situation just waiting to happen. Sure enough, a Centaur wielding a huge pointy stick struts in and immediately tries to impale Kratos. A quick half-rotation of the Analog Stick will save Kratos a world of pain. The horsey doesn't take much punishment before the QTE appears and allows Kratos to very brutally eviscerate the poor steed.

Pull the gleaming lever on the left to move one of the suspending platforms, and climb the ladder on the right. Do not tarry for long, as the platform returns back to its original position after a bit of time. Float over to the opposite ledge, upon which sit a chest teeming with red Orbs and a save point.

Gaia and Poseidon continue duking it out, but the tides of battle seem to be tipping in Poseidon's favor. Mash the Circle button and ride the retracting claw to an area outside. In part two of this battle, Leviathan has learned a few new tricks. The single claw jabs from before have multiplied into about three consecutive thrusts. In addition, Leviathan digs its claws in an alternating fashion to inch forward and ultimately trap Kratos within a confined area for its water breath. This will be devastating if Kratos lets this plan go into fruition, so he must relentlessly weaken the planted claws.

The QTE prompt appears sooner than you'd expect, but Leviathan isn't done. It continues its rampage, although becomes a bit more tame. Use magic attacks and commit a battery of attacks to bring up the QTE prompt once again. Mash the L1 and R1 buttons together to rip open the beast's chest. Approach the severed claw on the ground and press R1 to pick it up and fling it into the exposed cavity. Kratos pushes it deeper to add insult to injury and sends the beast to its final demise.

Climb up the vines along the weakened Gaia and enter her surprisingly hollow innards. Press up against the far wall and push through the tight squeeze. Locate the vine wall and follow it down into the Heart of Gaia.
