we're porting everything over first and getting everything working and then going from there. it's the easiest route to take for such a tiny development team (currently 2 people, plus a music composer who just came up yesterday).
once everything works, the weapons, maps, sounds, etc will all be remade/improved upon.
it's better to have 10 fully functional maps and all the weapons functioning correctly than to first work on a map from scratch, then create a single weapon, create the code for it. create another weapon, create the code for it, etc. we can work on more than one thing at a time.
