Frontline is a fun synthetic defense game. Today is the year 788 of the Starship Era. The Yuan Starship Alliance is to prevent alien monsters from invading the earth. In order not to affect the lives of people on earth, the Starship Alliance established the Interstellar Alliance in orbit around the solar system. The Star Alliance uses their powerful firepower to keep out all monsters that want to invade the solar system. All this is due to a very important technology of the Starship Alliance. The spacecraft they build can be synthesized. After synthesis, the spacecraft will become more powerful, even twice as powerful as the previous spacecraft. Starfleet Alliance and monsters are on par with this technology. But there are only 6 cabins, and these 6 limited positions must be used to combine into a huge spaceship. Therefore, what limits the development of the Interstellar Alliance is not the strength or the firepower, but the control of numbers. Come and try it.
