This game looks fantastic! It mashes up Diablo-like action RPG gameplay (plus the emphasis on monty-haul loot gathering) with tower defense elements reminiscent of 2011's fantastic Orcs Must Die! (click here to purchase for XBLA or Steam) from Robot Entertainment and emphasizes AFK multiplayer. You raid castles designed by other players to collect sweet, sweet epic loot to beef up your hero and earn goods to fortify your own stronghold against would-be raiders. Currently, it's in alpha (click here to apply).
