Crescent Moon is preparing to release Demonrock: War of Ages on the App Store tomorrow.
Set in a fairly traditional fantasy universe of elves, dwarves, and orks, the game turns the tower-defence mechanic on its head, getting you to charge towards you enemy's stronghold along a linear path.
Sometimes you need to capture your foe's base. Other times you simply need to slay everything on screen. Either way, you'll be peppering goblins with arrows and battering warlocks with clubs over 40 levels before you can say "one ring to rule them all."
See how I got on with Demonrock: War of Ages in the hands-on video below.
You'll be able to download Demonrock: War of Ages from the App Store from midnight tonight. It'll cost you 69p / 99c.
