Fieldrunners is a tower defense video game developed for several platforms. Originally released on October 1, 2008 as an exclusive iOS title, the game was later ported to Nintendo DSi, PlayStation Portable, PlayStation 3, and mobile phones. It was released on the Android platform in July 2011, on the Amazon Appstore and Android Market. On October 25, 2011, it was ported to HTML5 and released on the Chrome Web Store with the first level, Grasslands, playable for free. It is the first release of developer Subatomic Studios.


Fieldrunners offers three types of gameplay: Classic, Extended and Endless. Playing in Classic and Extended modes limits the number of rounds in which the player must defend to 100. Classic only lets players build the original four towers, Gatling, Goo, Missile, and Tesla (except Skyway which substitutes Laser for Tesla and Frostbite which substitutes Ice for Goo). Extended mode adds the two new towers, Flame Tower and Mortar Tower (except Skyway which adds Tesla instead of Mortar). In Endless mode, the player may defend indefinitely. In any mode, the player may play in Easy, Medium, or Hard mode.


Fieldrunners offers eight types of towers, each with unique abilities. However, only four towers are available for any particular map (six in Extended play). Towers are used to attack the enemy units and may be placed anywhere on the field. A line of towers may be created to force the land enemies to go around them, creating more strategy.

Name Description
Gatling Tower It offers a continuously firing attack, but is weak and has a short range.
Goo Tower It slows enemies for a limited period of time.
Missile Tower It is a splash damage tower and has a long range.
Flame Tower Capable of incinerating multiple fieldrunners in a single fiery swoop.
Tesla Tower Has a medium range, but it has the most nearby damage.
Mortar Tower Has a long range attack, but can't attack nearby. Highest damage.
Laser Tower Has a slow firing laser attack that pierces all fieldrunners in a line.
Ice Tower It slows all fieldrunners around it for a limited period of time.
Lava Tower It attacks all enemies in a circle around it.


In Fieldrunners, there were initially three maps a player could choose to play from: Grasslands, Crossroads, and Drylands. Grasslands is an open field in which enemies cross the screen from left to right, while Crossroads is set indoors where the player must also defend enemies going from top to the bottom of the screen. Drylands has three entry points, top to bottom, and one each at the top and bottom of the screen going left to right. Two additional maps have been added: Frostbite and Skyway. Frostbite has four entry points for soldiers. Skyway is similar Grasslands, with the exception of the former having obstacles already in the map. A recent update provided three new maps: Crystal Caves, MudSlide, and LavaFlow, along with the Shotgun Tower, Plasma Tower, and Lava Tower.
