In LegacySPORE, human mutants should be created as mutant animals, using the general rules update from After the Bomb second edition. Instead of using the human description there, however, use the statistics presented below. This plays off the mutant animal rules while still preserving aspects of the old method of creating human mutants.
As part of this rules update, options available to mutant animals are also expanded.
New Options for Mutant Animals
Add the following options to all other animals.
Human Features
Looks: The following options are available to non-human mutant animals:
[Partial -2] BIO-E for Androcephalic. Androcephalic characters have bodies and limbs with no human looks, but heads—particularly faces—with full human looks. Sphinxes are androcephalic mutants (often with the winged flight super ability).
[Partial +2] BIO-E for Hybrid. Hybrid characters have legs and feet with no human looks, but torsos, arms, and hands with full human looks. The head has partial human looks—though often appears human-like with bestial traits (ears, nose, horns/antlers, etc.). Fauns and harpies are hybrid mutants.
[Full -2] BIO-E for Zoocephalic. Zoocephalic characters have heads with no human looks, but bodies and limbs with full human looks. The deities of ancient Egypt were zoocephalic mutants.
In LegacySPORE, the only way a mutant animal can gain the traits of another animal is to select those traits as super abilities (such as Animal Abilities, Winged Flight, or the like)—BIO-E cannot be spent to develop such traits. Using a priority system to maintain balance, all characters have the chance to develop super powers and/or psionics.
