Berserker. Book 1. The Mask of Mars. Brother Berserker. Planet of Death

A long time ago, somewhere in the depths of the Universe, two races of intelligent beings met and began a war of mutual destruction, and they succeeded in this. The only legacy of that war is the absolute weapon that... ended it, killer machines endowed with computer consciousness. Moving through the Galaxy, these planet-sized ships destroy all living things in their path, because that is the main task programmed into them by their creators.
And now they have reached the outskirts of the space inhabited by humans.
Humans called them berserkers. Humans also know how to fight. Humans accepted the challenge.
This collection includes the first works of the cycle. In "The Mask of Mars," the human psyche will again and again have to engage in a duel with the no less sophisticated and contradictory psyche of the machines. In "Brother Berserker," the war will continue not only in space but also in time. And in "Planet of Death," a wounded and mad enemy ship will find a secret refuge and even create its own religious cult.
