Yes, the particles system in combustion 2 is based on Illusion technology, with a re-designed UI and a few new features, such as the ability to use any operator in the combustion workspace as a particle shape source (this brings up some very interesting possibilities, such as creating particle shapes using the paint module or using the text module to generate text-based particles, or even using another particles operator to generate particle sources).
Particle libraries from Illusion 2.0 are compatible and can be loaded into the combustion 2 particles operator.
