Cladun will be released only on PlayStation Network. It is a retro-looking dungeon crawler RPG with (almost) unlimited customization for your equipment, Magic Circle (character battle formation), character features, and even the last boss! The dungeons will randomly change all the time, so even if you re-visit a dungeon, the traps, enemies, dungeon map, and more will be different. It is a PSN-only title, but don’t underestimate its endless replay value! Check out the trailer below. Also, check back on www.nisamerica.com for the official Cladun website, which will launch around 5pm Pacific Time today!

your alittle late we already got the NIS press event down.

Oh it looks really good.

The co-op reminds me of Zelda 4 swords only with way more more customization.  I'm definitely intrigued.
