Overboard Trophy in Resonance: A Plague Tale Legacy

Kill 20 enemies by pushing them down a drop

Bronze trophy

Kick soldiers with off ledges or into spike traps. It counts only when the fall kills them, and pulling archers down from high places does not count. Ordinary soldiers are easy to kick. Those that hold a defensive stance are not.

A good place is Chapter V, Desolation It Wrought, sub-chapter Battle grounds. After the first fight, climb into the ruins, where spike traps sit in the floor among the soldiers. Before you kill the last of them, restart from the checkpoint (pause menu) and repeat.
