Pretty much everything from HL will be carried over by our mod in to our HL2 version. We are consider adding a new class of player not used in any mod we know of.
At least not the way we plan to use this class.
All of our mappers are amped to redo the maps for HL2, adding vehicles and more details and having a map out for HL already will help us ensure maps play as well as they look.
We are set and waiting for the sdk release and other items to get us started. If you want to join our team let me know.
