Wow, that's a lot of artillary that the nids are going to come up against. I will need to think of something clever to avoid having the poop shot out of my devouring swarm... Not setting up a room length apart will of course help.
I have been toying with buying some venomthropes. They're the ones that look a bit like an octopus and I quite like them. The only problem is that I am starting to want most things in my army now and need to stay a little more focussed.
Tonight I have glued together 4 little gaunts. Every little helps!
