It’s good that the game is still getting updated after all this time. Unfortunately, this is the final update.

From the press release:

    NIS America is happy to announce that the fifth and final update patch for Dragon’s Crown for PS3 and Vita is now available in Europe. This patch will introduce an entirely new difficulty mode with a raised level cap, address several gameplay elements, and improve on several features for the player experience on repeated playthroughs of the game. Developed by Vanillaware and directed by George Kamitani, Dragon’s Crown is a 2–D multiplayer action beat ‘em up from the developers of Odin Sphere and GRiMgRiMoiRe. Dragon’s Crown features breathtaking visuals that bring the fantastic characters and monsters to life with fluid artistry. Players can engage in local or online co-op play for dozens of hours of intense dragon-slaying action. For more information, visit http://www.atlus.com/dragonscrown
