Welcome to the year 2413 and this is not the total prosperity of mankind, as you might suggest. A few centuries ago, the Earth was under the yoke of an alien race, which is at a higher stage of development. People have not disappeared, but their numbers have declined greatly and now they are not leading the food chain, but have become one of the means for the aliens to live comfortably on the planet. The progressive part of the people did not accept the enslavement, went underground and continues to fight. Brave underground workers decided to use alien technology against themselves. A virus was created called xx142-b2. exe. This is a special program that is being introduced into a network of aliens and can deactivate the defense system by destroying energy generators. The invaders well defended their systems, in just 13 seconds the virus will be destroyed, but the whole trick is that it cannot be completely removed, clones are created that will do their job one way or another, and you will help them.
