Just a heads up that if you are making MP maps, to an extent you should go easy on the phys objects, dont forget to 'settle' them (so they dont drop when you load the map, see ( http://developer.valvesoftware.com/wiki/Map_edit ) to find out how.
ummm also start them asleep and use prop_physics_multiplayer for mp maps where applicable
Only reason i felt the need to post these 'tips' in a semi-related thread, is that ive seen too many maps that dont take it into consideration.

ive actually played a little bit of this on pubs, similarly to dystopia, its a ton of fun with a decent team, but the experience degrades sharply with the quality of your team.
