Square Enix has released a trailer for Heroes of Ruin, a new adventure featuring four unlikely heroes brought together to form a fearsome alliance. 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. Heroes of Ruin will be available for Nintendo 3DS in early 2012.
