The Entrencher is the players most important piece of equipment and it is used mainly for terrain deformation in combat (the creation of cover). However, outside of combat it also serves an important role in solving puzzles and gaining access to certain areas. It does not need any ammunition, but must recharge for a short time after excessive use. It's usefulness comes from its ability to create trenches and cover on the fly, giving the player a tactical advantage over Pacifican soldiers.
