Some RPG ideas, but my lack of AtoW experience shows.... :-\
FERAL SUICIDE PILL
The Feral Suicide Pill is a very potent but fatal cocktail of performance-enhancing drugs. Undercover agents can use these pills (or dental implants) to prevent capture or to allow the agent to achieve a critical objective. The pill forces an extreme boost to an users physical performance, but this reaction is so extremely destructive that it will kill them minutes after use. The chemical reaction will alter after the agent dies, quickly turning the bodily fluids into powerful acids and enzymes. This process will rapidly destroy the body, including the bones and any degradable items on their body.
Game Rules: Duration: 2D6 minutes (1 RPG turn = 5 seconds), followed by death.
Notes: Ignore Fatigue; Ignore Injury modifiers; STR +5; WIL +5; RFL +5; INT –6*; CHA –6* (*To a minimum of 1).
PERFECTED MUTAGENIC VIROTHERAPY
The Society had to flee the Homeworlds in defeat, but much was learned from the conflict. The data and survivors from the rebellion were enough for the Society to perfect Mutagenic Virotherapy. This allowed the Society to stop the usage of traditional Phenotypes and, at least internally, abolish the Warrior Caste. Currently all Society personnel are tested to find their specific combat aptitudes and are offered compatible perfected mutagenic virotherapies, called Mutatypes. Only one Mutatype can be selected for implementation and they can't be passed down to offspring.
Berserker Mutatype
Users of the Berserker Mutatype are often nicknamed Hyper-Elementals. On the outside they look like regular Elementals, but on the inside their bodies aren't fully human, but use biological adaptations from all over known space. This allows them to match the performance of Pain Shunt, Full-Body Dermal Armor and Triple-Strength Myomer Implants. But with the side-effect of permanent sterility.
Notes: Equal to Pain Shunt, Full-Body Dermal Armor and Triple-Strength Myomer Implants. Toughness, Sterility
Gunslinger Mutatype
The Society sees the Gunslinger mutatype as a generalist option. It improves reflexes, general senses, dexterity, multi-tasking. However there is a significant downside to having the muscles and nerves optimized for speed and accuracy, as these adaptations will reduce the maximum amount of physical muscle strength that the user's body can produce.
Notes: RFL +2; DEX +2; STR -1; Traits: Good Vision, Good Hearing
Interface Mutatype
This mutatype enhances neural tissues to improved compatibility with neural implants, while also preventing deterioration of mental health, feedback damage and the negative side-effects of Feralize drugs. It is used by all Society ProtoMech pilots and most Mechwarriors. However researchers have noted an increased risk of interface addiction, in where users don't want to disconnect.
Notes: Immune to neural feedback and side-effects of feralize drugs; Traits: Poison Resistance, Pain Resistance
Spacer Mutatype
Fully organic but based upon Belter adaptations, this Mutatype goes one step further in making people more compatible with the environment of space. It is mostly focused upon improving low-G, high-G tolerance, oxygen consumption control and temperature regulation. The notable side-effect of these adaptations is full body hair-loss, also known as Alopecia Universalis.
Notes: Trait: G-Tolerance, Thick-Skinned, vacuum exposure protection (1hour).
