Do you know how to assemble robots? Humanity was wiped out on Earth by uncontrollable AI combat robots. Only the descendants of criminals sent ahead to build a city on Mars have survived. Unlike those content with a stable life on Mars, you lead a spaceship to reclaim Earth. To build a robot army, you can create combat robots by assembling various robot parts at the repair shop. You assemble a robot by attaching five different types of parts to eight different body parts. The metal materials consist of copper alloy, steel alloy, and titanium alloy, each differing in durability, specific gravity, and price. Each part can be repaired by purchasing raw materials from the black market. Even during combat, you can board a robot onto the spaceship to perform repairs, recharge, or replace parts, and then sortie again. Robots can move in walking, flying, diving, and burrowing modes, and each part is specialized for air, water, and land. To possess special movement abilities, you must attach Jet, Dive, or Drill parts to the back part. In particular, in diving or burrowing modes, movement is possible while stealthed. However, you may be detected if the enemy has a detector. Submerged hostile units can see each other underwater. If you can see them, you can attack them; if you cannot see them, you cannot attack them. Each part made of copper alloy, steel alloy, or titanium alloy has different durability and weight, even if they share the same design. Increased weight increases battery consumption for all actions. The robot's core part is equipped with a battery; if the core is destroyed or the battery is depleted, the robot becomes uncontrollable. The robot's battery can be recharged on a spaceship, and if the spaceship's battery is depleted, the robot cannot take off from the planet. In that case, you must secure emergency power by manually rotating the generator. Of course, you can increase the automatic charging capacity by upgrading the space battleship's solar panels. Once you have built a sufficient robot army, you can participate in the Battle for Earth Liberation. Before joining, you must assess the terrain, secure sufficient batteries, possess superior combat power, and have resources for repairs. A significant amount of funds is required to build a sufficient combat force. To secure funds, you can collect scrap metal from the lunar ruins and sell it on the black market. You can earn a large sum of money by participating in and winning robot duels. You can receive money from the Mars City Alliance by eliminating pirate robots that have invaded Mars. When purchasing parts or resources on the black market, you must monitor price fluctuations. Price fluctuations occur independently for each resource, and the magnitude of these fluctuations increases as the scenario progresses. Parts in the black market have limited stock, so if you absolutely need them, you must buy them in advance, even if they are expensive. Also, since a profit margin applies, you cannot receive the same price you paid when selling them, so you must purchase only the parts you truly need. The enemies establish their formations around space battleships and organize dedicated defense and reconnaissance units. Since enemies flee when at a disadvantage and cooperate to attack, reconnaissance is crucial. You can analyze the battle map in advance in the briefing room to gain an advantage in combat. If there are many mountains, you can use tunnels, and if there is a lot of sea, it is best to move underwater. The best method is flying, but it consumes battery power extremely quickly. Diving significantly reduces battery consumption and offers the advantage of stealth. Tunnels allow you to stealthily infiltrate behind enemy lines, attack targets, and then stealthily exit. When attacking enemies with melee weapons, you can choose which of the eight parts to attack. The enemy's weak point is the core, making it the top priority for attack; however, since it has the highest durability, you must examine the enemy's weak point. Legs provide movement ability, the head provides vision, the arms provide action ability, weapons provide attack ability, and the back provides special abilities. Since the corresponding ability is lost when each part is destroyed, you must first decide which ability to remove. Conversely, you can use your arms for defense. If a shield is equipped, its durability decreases, and you can also defend with a weapon. You must utilize terrain advantages in combat. Hills increase defense and attack power. Streams decrease defense and attack power. Flying units do not receive terrain advantages. Submerged units and units underground have high defense. Incapacitated enemy robots are treated as scrap metal and can be brought back to the space battleship. Conversely, the enemy can take your disabled robots, dismantle them, and assemble modified robots to attack you. The ultimate goal of this game is to use a robot army to reclaim Earth, which has been overrun by uncontrollable robots. The scenario mode consists of a total of three parts, with 10 stages provided in each part. As the parts progress, the difficulty increases and the scale of the battle map expands significantly. Since there is no limit on the number of robots you can deploy, you will engage in large-scale battles. Can you overcome rising prices, enemy AI, insufficient power, and scarce resources to reclaim Earth for humanity?
