it's pretty much an action-RPG, Diablo-style, or Soma Bringer, if you are more familiar with that DS game(you should try it if you haven't), BUT with online capabilities, using 3DS' wi-fi and streetpass/spotpass features. you can choose between four classes, customize the crap out of your character, then either dungeon crawl solo or jump online and get a team!
more details(copy-pasta from IGN):
Heroes of Ruin, a brand new adventure featuring four unlikely heroes brought together to form a fearsome alliance.
Heroes of Ruin uses StreetPass to create an inventive in-game Traders Network where players can buy and sell rare and powerful items picked up in battle. With an ever-changing inventory updated from each player passed in public, character strengths and abilities can be greatly enhanced through accessing items from other players’ games. Outside of the game, Heroes of Ruin makes use of SpotPass to reward players with rare one-off items or unique challenges through local wi-fi hotspots. The official Heroes of Ruin community website will reward players further with daily challenges and quests available to complete in-game. With social media functionality, the site will also give players a platform to meet other gamers, swap ideas and items and team-up in-game.
Heroes of Ruin challenges players to carve their own adventure, joining forces with other heroes through seamless drop-in/drop-out co-op multiplayer or venturing forth alone. Players will enter an ever-changing world where danger waits around every corner. Heroes can explore and fight through wild, varied and dynamic environments, discovering new layouts and routes each time they play. Packed with strange and deadly creatures, these dangerous lands will stretch players’ combat and tactical skills as they enhance their character, collecting loot, weapons and armour to empower them on their quest.
story (copy-pasta from the website heroesofruin.com):
War raged for over a hundred years until strong, powerful Lords emerged from the fighting to bring a fragile peace to the land. This peace is threatened when one of the Lords, Ataraxis, ruler of the city of Nexus, is taken ill by a deadly curse. A call is sent out, promising rewards beyond measure for anyone who finds a cure.
Four mercenaries, each with their own strengths, weaknesses and motivations answer the call. One uses forbidden spells to rain death on her foes, one has guns and bombs to blast his way through, another has a mighty sword capable of slicing through entire packs of enemies, and one other gains strength from savagely tearing through anything that stands in his way with brutal, bladed fists.
release date for US region is June 26 2012, but it has been delayed a couple of times, so I wouldn't be surprised if it was delayed again. I'd rather have it delayed, with the bugs ironed-out.
anyway, check out these trailers!
