NIS has teamed up with Acquire to do something completely different. Clan of Champions (or Gladiator VS as it's known in Japan) is a medieval-themed third-person action-adventure game in the same vein as Demon's Souls. The game can be played solo, but it seems that you're encouraged to play with up to two other people. I only played single-player, but Spencer over at SiliconEra informed me that it's best to play with others to get the full experience.
Combat for the most part was pretty challenging. Something I found cool was that your and your enemy's shields and armor can be broken during fights when they've taken too much damage. Losing the armor does mean you'll take more damage from enemies, obviously. I also found it neat that you can take any weapon you come across, like ones from fallen enemies. You may just want to focus on a few weapons though as the longer you use a weapon, the more skills and moves you'll learn for it.
