On topic: the map is beautiful, posted in the OP, and hopefully can be textured (or built, even) to something acceptable and perhaps even interesting by Deus Ex lore.
I had to do a bit of reading on
Assault game type since I haven't really played UT. Seems like general-purpose game type that would definitely be welcomed in DXMP, but please don't do something stupid like importing UT vehicles or whatnot, unless they make sense in the year 2050, in Deus Ex.
So as far as THIS particular project goes, I support it fully just as long as it supports auged Deus Ex and maybe, maybe, 0augs as well. The idea behind Assault game type is great in itself.
Slightly on-topic: STALKER is a complete waste of your time, if you want to work on it so that you could learn more and enjoy yourself, its ok, but nobody will bother playing it.
Do it vice versa: build DXMP in STALKER, and *then* we're talking. Likelyhood of success when working alone is not great, though.
