In the game, a mutant is a specific monster, not a class of monster.
- "It seems that the proposed method of mutation leads nowhere. Fast, agile and aggressive creatures are born as a result of the transformation; however, they lack intelligence. They are closer to animals than men. Of course, that does not mean we will not find any practical use for them. On the contrary, simplified mutating procedures guarantee that we can create many Mutants, which are perfect tools for spreading chaos and terror."
