The “Maxed Out” trophy in God of War III can only be obtained after completely upgrading all your weapons (or so you would think). A forum user at PS3Trophies.org has discovered an alternative method to acquiring the trophy (see below). The glitch appears in Combat Arena, which will be unlocked once you beat the story and Challenge of Olympus mode.
To activate it, set Kratos’ health, magic and item meters to “Level 1” in addition to putting the difficulty to “Titan.” Pick whichever enemies you wished to fight and then start the match. In the arena, simply die over and over again until the game prompts you to switch to Easy Mode. Choose “No” to return to the title screen and the “Maxed Out!” trophy prompt should appear a few seconds later.
Naturally, Sony will be looking to patch this glitch pretty soon so make use of it soon (if you don’t mind cheating).
