"Wha... ...ed? Thi... Tanegashima!" Those were the last words from the spaceship Tsuwabuki. The spaceship lost control, and the twinkles of stars flew past the windows in all directions. Suddenly, the spaceship shook violently. Aki was thrown about before she could think. She quickly lost consciousness. In this game, the players work together using the Rovers to help rebuild the spaceship. The asteroid is far away so the players must send their commands to their Rovers at once. Then the Rovers will carry out each step. So the players must plan ahead and guess the future. But sometimes the commands are lost. Solar winds, or sandstorms on the asteroid might disrupt the programming. A Rover might break down. Let’s join forces, work as a team, repair Tsuwabuki, and bring our friend Aki back to Earth. Project: RETURN HOME. The game consistes of some roles, one is a Monitor and the rest are Rover players. The Rover players select and put three cards face down from their hand choosing from: "Run","Survey", "Repair" and "Recharge Battery". Then the Monitor chooses 2 cards to avoid from the 5 disaster cards in a row. The remaining three disasters affect the Rover player's cards in the corresponding order. So, if the disaster is a sandstorm, the player who chose "Run" will take damage. Actions may be canceled after the Emergency. In addition, players should be aware of Astronaut Aki. The Oxygen is limited. You have to find materials from the asteroid and supply the oxygen before it runs out. Find and assemble the Spaceship parts before all Rovers are destroyed! And let Aki return home! Then, players win the game!
