"The Watchman of Earth” is a fantastic novel by Denis Deev, the first book of the eponymous cycle, genre: combat science fiction, RealRPG. We lose the war—not because we have bad weapons. Our weapons are a fusion of advanced Earth technologies and alien artifacts. Our Outposts are impregnable fortresses that can withstand sieges for years. An elite serves there—top scientists and warriors on the planet. But we lose battles because we can’t understand the enemy’s logic. Why do the aliens selectively destroy certain biological species but leave others alone? Why do they make us stronger from battle to battle? Fighting is hard when your enemy is unknown… but our armor is solid and our mechs are fast!
