"The Outlander" focuses on the artistic value of video games, using the highly customized Source Alien Swarm Branch engine that we have heavily rewritten, and positioning itself as a narrative game focused on artistic expression. On the basis of the play feel recognized by the relevant units in the northern war zone of the Chinese people's Liberation Army and striving for realism and fun, we focus on the narrative itself, trying to support a repeatedly polished story with the most basic play, and use our long-accumulated rich experience to create a work worthy of repeated aftertaste. Not only that, in order to implement the fundamental policy of "pursuing the best performance effect and plot impact", we have repeatedly polished a script and setting for "strangers" that can withstand scrutiny, but also injected many cutting-edge productivity technologies accumulated and summarized in long-term practice. In view of the basic engine rewriting and development work belongs to the basic development category, it will not be repeated in the following. Next, we will select representative technologies that can reflect our creativity and challenge spirit, using a series of advanced technologies in the industry, such as motion capture, facial capture, model scanning and so on. In a world of loyalty and friendship, intrigue and betrayal, the player's every decision counts. Each inadvertent choice may affect the direction of the story and lead to a different ending that belongs to each player. In the multiplayer mode with different styles, players will, as a member of the participating team, personally participate in an international military competition related to national honor, and strive to use their hard-trained skills to make the balance of victory fall to their own camp. At the same time, the weapons in the hands of the players and the tactical vests on their bodies can be customized as needed.
