This achievement can be earned by simply following the main story until you have to find the final item for rewriting reality. Alan is directed to an old train station near the train tracks. When the player approaches, a Splitter will bust through the door. Make sure that you have the shotgun that can be found across the street from the motel. Be sure to shine your light on the splitter to make him break apart, you may want to do this again as it makes each form weaker. Simply wait for two of the forms the group up, then shoot them with the shotgun.
