Working out the best way to make your enemy's journey as long and painful as possible is almost like a tricky puzzle, and no two solutions will be the same. This entails a certain level of creativity - especially when levels come with pre-built structures like bridges and trenches. You can spend money that you earn from gunning down enemies on more cannons, flamethrowers, and sticky glue guns to craft your corridors of doom. As you work through the story you're often presented with an empty field to paint as you please. You were effectively making the queues from Alton Towers, only lined with machine guns.


This meant you could build your own paths by carefully placing down lines of turrets, ferrying baddies into snaking corridors and trenches. The first Fieldrunners turned tower defence on its head: instead of marching along pre-built paths, invading marauders would make a direct beeline to your base.
