The ability to play as a Super Mutant, Ghoul or human. Ghouls and Muties would have special abilities that could be used once every 12 hours. As a mutant you could choose Nightkin or Basic. Nightkin would be able to become invisible for a a while and only be able to do so every few hours. Basic mutants could use a rage ability. Ghouls would be able to be basic ghoul or glowing one. Basic ghouls would able to go "feral" making them take less damage while dealing more, but they become unarmed. Glowing ones would have the radiation nova, healing them and damaging enemies. All types of mutants would be immune to radiation and at higher levels would gain the ability to be healed by it. The biggest downside is that unless your reputation was extremely high, most towns would open fire and attack you on sight and you would be very suseptable to racism or bigotry even if your reputation was good. Also, as a super mutant you would be unable to wear most human clothing or armor. I would love for someone to give me some more ideas about this and maybe some criticism.
