Publisher Armor Games and developer Ironhide Game Studios have announced that the award-winning app Kingdom Rush is now available for free, for a limited time only. Normally $0.99 on the iPhone, the full tower defense classic can be downloaded free of charge.
The promotion is only for the iPhone version, though the game is also available for the iPad and iPad Mini. Kingdom Rush has been optimized for iOS 6 and iPhone 5, featuring retina graphics.
For those new to tower defense games, Kingdom Rush offers a unique blend of simplicity and challenge, making it appropriate for both newcomers and tower defense vets. The game boasts a lengthy campaign, backed by Heroic & Iron Challenges. For those who are looking for an even greater challenge, I task you with earning up to three stars on each level to receive the permanent upgrade on your towers.
Armor Games hasn’t said how long the game will remain free on the iPhone, so I suggest heading to the Apple Store and downloading it immediately.
