Today, developer Phosphor Games Studio (makers of The Dark Meadow) released the latest trailer for Horn, its action-adventure title coming out for iOS and Android this month.

Horn features an open fantasy world with “10 hours of story missions, plus endlessly escalating challenge modes,” Phosphor said in its announcement. Zynga will publish the game as part of its Partners for Mobile program, which easily makes this the FarmVille developer’s most hardcore project ever.

From today’s press release:

Based loosely on the Old English tales of King Horn, you play as a young blacksmith’s apprentice who wakes up to find his village overrun by fantastic, and sometimes humorous, monsters. On your incredible adventure, you carry the loud-mouthed head of one such creature with you — a somewhat uncooperative, ill-tempered, grudgingly helpful sidekick. Along with the help of this new companion, you must use your sword, crossbow, trusty musical horn, and wits to explore the lands, defeat the enemies, and solve puzzles in your quest to undo the curse that engulfs your homeland.

Here’s hoping developer Grasshopper Manufacture doesn’t hit Zynga with a lawsuit claiming infringement upon its own games, Shadows of the Damned and Lollipop Chainsaw, both of which also feature severed heads as sidekicks.
