App Description

★★★★★ "The graphics and music are great and the unique controls and gameplay tie it all together in a perfect dungeon slasher package." —AppAdvice

“This is zombie slaying at its purest.” —148Apps

“One of the most streamlined experiences in the genre on the iPhone.” —AppStorm

“Simple and fun…like a hack-and-slash version of Canabalt.” —SlideToPlay

Zombie hordes roam the dungeons, slouching and gnashing and smelling just awful.

Survive their endless onslaught in this indie fantasy brawler.

Become Thorn, viking hero of notably short temper. Trapped in the zombie dungeon, you must employ a vicious arsenal of axes, blades, and bombs to hold off hordes of the undead.

▶ SURVIVAL MODE (free): Find the exit before time runs out! Fight your way through zombie hordes in an infinite series of procedurally-generated dungeon levels. Prove your might and best your friends with impressive high scores on Game Center.


▶ ESCAPE MODE (in app purchase): Defeat the Evil Lord Evil and escape the Dungeon of Bad, with multiple lives and no per-level timer. New dungeon zones, new monster types and boss fights, new weapons and levels and gameplay. More Thorn than you can shake a stick at :)

Thorn is ONLY compatible with 3rd-generation iPod touch, iPhone 3GS, 4th-generation iPod touch, iPhone 4, iPad, and iPad2. The 8GB 3rd-generation iPod touch is unfortunately NOT 3rd-generation hardware, and thus Thorn is not compatible with it.
