Welcome to Librarium Online!
Just wondering what you guys did for terrian, as I'm thinking of starting a table
Only a few prefer liberty - the majority seek nothing more than fair masters
I have done several different terrain items for Necro: sludge lakes, old ruins, a tunnel, odd bits and pieces of cover, an old water tower (counts ingame as a watersill) and lots more. At the end of the day your imagination is the limit. Read some Necromunda novels/comics and have a good look online at some of the terrain other people have made for inspiration. Also, read through the territory section in the LRB and see what your mind pictures... then make it!
The great thing about Necromunda is that Hive Primus is a HUGE place. The differing varieties of structures/architecture/ruins etc there are almost endless. One thing to keep in mind is that the areas are almost always dark and dingy, with very little (or indeed nothing) new and shiney. Make metals rusty, corners mouldy and alleys dingy!
There is plenty of stuff on the net to read bout Necro, just google it and see. I wrote a short article about a settlement in Hive Primus for the specialist games site competition. I didnt get into the finalists, but if you want a copy to see if anything in there inspires you to create terrain then I am more than willing to email you a copy, just PM me with your email address (that goes for anyone who reads this).
Good luck with the terrain.
Hope this helps.
