The D.E.M Engine employs a dice pool system (but never more than 8 dices) and is extremely versatile. The fight and flight system is still there, and so are most other features. Vivisection will be updated and made into a pdf, while NPLH will use the D.E.M Engine in pdf version from the start. However, it might be possible that we will provide a free stat sheet using the old rules for both Vivisection and NPLH so those that have the first English version will be able to use the D.E.M Engine versions as well.
And Cold & Dark is moving forward and this game has a lot of potential
