i haven’t done map editing since doom,
so im gonna make a suggestion to other mappers,
ice tram and assault would make a cool ET campaign,
MP_ICE, MP_TRAM, MP_ASSAULT as one campaing would rock
hmm i think copying maps from rtcw is both lame and inspirationaless
i think that ET is desinged for new maps not those old ones from rtcw 
as a capaign it would work well i think also.
however a direct copy of the maps in to ET wouldn’t work well because of the class structure, and extra things available in ET. you may as well just go and play it in rtcw with a 3 map cycle.
If you are planning on converting maps from game systems then a mapper should consider the following points:
• The spawning system is simpler and uses fewer entities.
• Command posts. (either neutral or individual)
• Health/ammo cabinets. (Can be linked to constructions if necessary)
• Map objectives should be set up to use the limbo camera system.
• The construction system is a critical component in Enemy Territory and all maps should be designed with this feature in mind. (This a feature of the Engineer class only)
• Command map - all maps need to define the co-ordinates of the command map so that the map will load correctly and work with the limbo menu.
• Maps loaded from the in-game menu system need an arena file.
• Enemy Territory supports script moveable objects. (vehicles)
• Environmental effects like rain/snow.
• New fog system which works with multiple pass shaders and lightmapped terrain
• Support for model foliage via a special shader. (Compiler option)
• A new class has been added to Enemy Territory called CovertOps. Team doors should be added to critical choke points in maps so some objectives can be bypassed.
• The terrain system can have external lightmaps and decals.
• All maps need a special “trace map� for the mortar and environmental effects to work.
• The shader language supports implicit shaders. This can affect how models and surfaces are lit in the game.
• New scripting commands to enhance the existing RTCW system.
• New compiler and GTK plug-ins and features.
• Land Mines and new surface parameters.
As you can see, there is many points to consider about new maps for ET and simply cutting and pasting a map from another game is not the answer. If people are stuck for ideas and then I suggest trying the following link…
