To unlock the Combat Arena, complete all challenges.
Godly Possession locations:
Collect the following Godly Possessions to unlock the corresponding effect after the game has been completed. The Godly Possessions must be equipped in the “Items” menu for their effect to become active:
GODLY POSSESSION – LOCATION
Zeus’ Eagle – Unlimited Rage of Sparta.
Hades’ Helm – Maximum Health, Magic, and Item meters.
Helios’ Shield – Triple the Hits counter.
Hermes’ Coin – Collect ten times the amount of Red Orbs.
Hercules’ Shoulder Guard – Decrease damage taken by 33%.
Poseidon’s Conch Shell – Unlimited Magic.
Aphrodite’s Garter – Continue to use Athena’s Blades.
Hephaestus’ Ring – Automatically win all context sensitive attacks.
Daedalus’ Schematics – Unlimited Item meter.
Hera’s Chalice – Health meter slowly drains over time, but never completely emptying it.
Extra Red Orbs:
When fighting those sword-wielding Olympian skeletons, kill some so that there about ten left and position Kratos with his back to to a wall. Equip the Claws of Hades (which need to be at level 2 or higher). Repeatedly lash out with the Soul Rip (L1 CIRCLE) and you’ll get hundreds, even over a thousand hits on just a few enemies. The Soul Rip attack deals very little damage. On hard modes you can probably increase the hit count further and be rewarded with more red orbs. Note: If you don’t back against a wall you’ll have to move towards enemies a bit after each attack.
Mysterious Website for Platinum Spartans:
If you get the Platinum Trophy in God of War III you’ll be directed to the following website featuring only a compass and falling rain:

New Game glitch:
There is no New Game option but you can do a glitch that gives you maxed out weapons and infinite magic at the starrt of the game. First you must unlock the Combat Arena. Set magic to infinite. Get killed in the Combat Arena 5 times so that the game asks if you want to switch to easy mode. Choose no. You should be at the main menu now. Start a new game on whatever difficulty you were on during the Combat Arena. You will begin the game with all weapons maxed out and infinite magic.
