Expanding knowledge: On June 65438+1October 19, 2022, we crossed the FireWire HD (CFHD for short) and officially opened a new chapter of the plot challenge mode "Crossing FireWire: Ghost Plan" (referred to as "Ghost Plan"). This is the second chapter of the single-player campaign plot launched by CFHD after crossing the line of fire: fuse. The story will lead the player to uncover the origin of the ghost with the end of the fuse. In the last chapter "The Fuse", players have a preliminary understanding of the composition and origin story of the world view of crossing the line of fire from the perspective of three defenders, and deeply explore the essential reasons for the protracted conflict between defenders and infiltrators. In this Ghost Project, the player's perspective will shift to the infiltrator's side, focusing on the story of the origin of the "ghost" in Crossing the Line of Fire, so as to further understand the conceptual conflict between the infiltrator and the defenders. At the same time, players will also have the opportunity to experience the unique fighting style of the role of "Ghost".
