Biotechnology, or Biotech, covers a broad spectrum of organic-based tools, genetic engineering, and cloning processes.
Starting characters may genetically engineer their character to have better Attributes.
Dead characters may be cloned. If their brain is still intact or preserved within 6 minutes of death, they can even be resurrected. However, without the proper medical equipment this is impossible.
Some species have been mutated due to certain types of radiation to create mutants, or through genetic engineering to create new subspecies which breeds true. Whether they are genetically engineered or mutated, they are still called Mutants.
