Trench Barrier is an ability of Footbot's in Minion Warfare. Footbot uses a trowel (seen in his ammo case) to create a ring-shaped mound of dirt around him, regardless of whatever terrain he's currently standing on. This mound is almost as tall as he is, yet still short enough to jump over. He can jump out of this small fortress to fight elsewhere, and any other player (friend or foe) can use it as cover. It can not be destroyed, but it will disappear after a short while.
