Here goes, my first attempt at putting together a terrain piece. I use the 'Nid terrain bits from the Battle for MacCragge box set. I give you, the Tyranid ravaged landscape! --DF2K
That is the ideal terrain piece my friend. Great detail, looks great and ISN'T CLUTTERED! It would be sooo easy for your tyranids to move through that, while receiving their cover saves of course Nothing more frustrating than carefully placing all manner of boulders and trees and rubble across a terrain piece, the odd ruin here and there, and then having all your models just fall right over because they don't have level ground to stand on... Of course, you could make metal buildings and magnetize the bases of your tyranids... Genestealers running on the side of a building would be awesome!
