Fieldrunners is a real-time tower defense game with open field style maps. It is currently on iTunes for $4.99. To find out more, take a look at the Fieldrunners Review.

The goal of Fieldrunners is to stop the attackers, ie: fieldrunners, from crossing the field and entering the gates at the opposite end for 100 rounds. If 20 fieldrunners enter your gates, you lose.
These tips apply to version 1.1.1 of the game.
These are specific walkthrough guides for completing various maps of Fieldrunners. It is suggested that you only refer to these if you're getting stuck/frustrated :)
Although we love to play by the rules, and obey all laws, there are times when some laws must be slightly bent... for the people of course. UPDATE: The Fieldrunners 1.2 update pretty much destroys this cheat as the game now saves every round.
