For the first time in 18 months, Fieldrunners for the iPhone/iPod touch has received an update. Version 1.6 includes a number of new features including the addition of full Retina display support.

Created by Subatomic Studios, Fieldrunners is a tower defense game featuring soldiers, each with a gaggle of new tricks. Your job is to defeat the enemy, and thereby save the world.

According to Jamie Gotch, CEO of Subatomic Studies:

Not only did we completely redraw the artwork in a higher resolution for the Retina display, but we also added the full soundtrack for the first time ever on iPhone, and added support for 32-bit colors [on the iPhone 4 and up] to give fans richer environments, enemies, and towers.
