Every piece of terrain needs to be no bigger than 12"by 12"and no smaller than 6"x 6"
the proportions can be adjusted, for example minimum 3"by 9", max 6 "x 18" but stay within those parameters.
You will be assigned at least three 40k rules that the terrain must represent!
Every piece of terrain needs to be based around the theme of JUNGLE RUINS.
Good Luck and Have fun!
