*The game is still under development, the English localization is not completely ready, there may be some translation errors and untranslated texts in the demo, we will update it as soon as possible! As an RTS strategy game, Deep Dark Forest includes elements of exploration and expansion, combat, construction, technology development, and management. But the gameplay design inspired by the &quot;Dark Forest&quot; law in the famous science fiction novel: &quot;The Three-Body Problem&quot;, differs the game from the traditional RTS operation of troop combat, with more emphasis on the collection and analysis of information, and the choice of strategic choices. In this universe with the &quot;Dark Forest&quot; law, players need to carefully build economic, scientific research, and military facilities and choose the congressional bill to meet the situation, to improve the economy, develop technology, protect the people, and maintain social stability. However, although the universe is infinite, the resources in a certain area are always limited. In order to survive, exploration, colonization, and expansion are inevitable steps. Sending out exploration satellites to gradually explore the unknown areas around; building military bases, spaceports, and other facilities for force invasion and immigration, how to balance resources, and deciding the direction of science and technology is crucial. And in the process of development, expansion and war, it will certainly be accompanied by the problem of depleted resources, reduced cohesion and increased pressure of social opinion. If these problems are out of control, your civilization will fall apart from within. How to balance all aspects, depends on the player's wisdom. However, because of the &quot;Dark Forest&quot; law, all civilizations will deliberately hide their traces and information in the universe. Such as the environment of their galaxy, the state of civilization, and their actions of each round, the player will have very limited access to information. Therefore, by developing technology and exploring, players need to try their best to collect and integrate information and make decisions at the strategic level. Especially when you encounter a civilization, do you want to stay silent and hide in the shadows, or do you want to communicate with it and risk exposing your coordinates to gain more information and benefits? Your decision will affect the survival of the civilization. For an unknown civilization in the universe, if it is just a fleet attack, highly developed technology level may be able to help you detect the actions of the other side, defend your homeland and win the war. But what if it's a mass bomb big enough to destroy the galaxy? Or what about an almost unstoppable light particle attack? Whether your civilization believes in science or gods, whether you are a galactic dictator or leader of the united nations, whether you rule by force or govern the galaxy peacefully, the exposure of coordinates means that your civilization is in danger of destruction at any moment. Of course, you can also broadcast your rival civilization's coordinates, hide in the shadows and let others help you to take down your enemies. Hidden and exposed, peace and war, friendship and betrayal, your civilization, your decision. The future of civilization is in your hands. When a friendly greeting comes from a distant galaxy, will you respond or remain silent? The civilization that triumphs is not necessarily the most powerful civilization, but the one that hides the deepest dark corner and lives to the end! Deep Dark Forest hopes to give you a true sense and understanding of the laws of the &quot;Dark Forest&quot;, and to show you how opaque information is in the world of the &quot;Dark Forest&quot;. <ul class="bb_ul"><li>With different from the previous RTS strategy games. </li><li>The design of the &quot;Dark Forest&quot; from the &quot;Three Bodies&quot; brings a unique gaming experience. </li><li> The information is highly hidden and needs to be collected and analyzed by the player. </li><li>A wide variety of technology brings different strategy options. </li><li>Up to 8 players can play against each other in PVP, so you can experience the most realistic &quot;Dark Forest&quot;.</li></ul> <ul class="bb_ul"><li>Ten single player chapters with unique stories </li><li>A civilization creation system that allows you to create unique civilizations with different types and numbers of ideas according to your preferences </li><li>10 different civilization trends (exclusive skills/technology, etc.) and over 90 combinations of trends </li><li> More than 170 unique civilization stories can be created </li><li>35 types (500+) of technologies to develop and upgrade </li><li>Fast-paced, high-intensity confrontation, 30-60min/game </li><li>Completely randomly generated maps, making every battle a different experience.</li></ul>
