Captain:Training

In 2045, a UFO suddenly appeared in the solar system. It was immediately discovered by the earth and was identified as an extraterrestrial creature. The object then changes its orbit, rushing towards the earth, rushing into the atmosphere at a speed that human beings do not understand, turning itself into a meteor and burning into nothing.
The various sides of the earth responded differently, but someone created the Global defense company and began to use computer games to screen and train volunteers. This is the original version: the captain - the training.

Use your resources, choose your spaceship, become a captain, train yourself, feel the laws of the universe, improve your captain's skills, wait for the calling.
