The Elite update for God of War: Ascension is available today, and with it comes a new level cap at 40 instead of the prior 30. That makes for a pretty big chunk of levels to grind through, so Sony has decided to give a leg up with a double XP weekend as it kicks off.
An in-depth (and gif-heavy) blog post details the update. The double XP weekend will last from today through Monday at 10 AM PST. The full change-log is lengthy, but it notably fixes some exploits like one related to the Spear "air" Heavy Attack and audio issues. It also adds a handy stats card for keeping track of your vital information. It also adds a "Game Mode Inspect Card" to give a clearer idea of your objective in each game type.
