I am working on a system shim to use Cortex Lite with Mutants in the Now.
Mutants of the Now uses a sort-of modified Palladium system (since it's a spiritual successor of TMNT). For the right group, it's very good.
For the group I'm aiming for, less so.
Most of the basics work in Cortex Lit as is. One distinction will be "Mutant Animal" where you replace "Animal" with the type of animal you are (like "Mutant Ferret"). The other two are the standard belief behavior quirk.
Each character gets a fighting style which will be one of their starting specialties.
The rest of the character is made as normal in Cortex Lite except...
