Sharrash: a mysterious yet well-organized community of mutant rats characterized by superhuman intelligence. They live underground, in the tunnels and canals of the destroyed cities, accompanied by their servants: degenerate humans and mutants. They do not allow strangers anywhere near them, fiercely defending their nests, and their fighters will not hesitate to offer their lives to the pack. The Sharrash rats are not mere animals - they are mutants who are smarter than humans and far less predictable. And now they have entered the Neuroshima Hex world.
