To exceed the usual 50 kilograms of weight you can carry, simply load excess weight on to a human corpse. Then press [Shift] + [Use] to drag the corpse along with you. By doing this, you can load a corpse with any number of items and move them from one location to another. Note: Because you cannot attack while dragging a corpse, use this trick only when there are few enemies around. Additionally, you cannot drag the corpse into a new map. Do not leave items you want to keep on a corpse or they will be lost when you enter a new map.
