yeah, I'm going to play an apocalypse match soon, and my nid opponent will bring 20000 pts, which will include something like this:

-1 biotitan (i think it's called a hierophant)
-2 hierodules
-one of those flying gargantuans
-endless swarm
-about 200 genestealers...

I dont' know what to do to kill the biotitan... 10 wounds, and it regenerates...

I have no superheavies myself
