Gameloft's free fantasy hack-and-slash game, Dungeon Hunter 3, now lets players team up or duke it out online with new co-op and competitive multiplayer modes.
As usual, you chose one of multiple standard classes, and defend against waves of monsters for as long as your weapons, armor, and powers will allow you.
As with most of Gameloft's free titles, this one's rife with in-app purchases, but I never found them particularly intrusive in the time that I put into Dungeon Hunter 3. To start slaying some dragons with buddies, hit up the download link below.
