Just a kind of general list I was considering taking for the nearing ard boyz, I find it to seem WAAC for tyranids but is it win-able? I thought swarm tyranids were getting kind of old and managable, yet I looked in my box of stuff and found stuff for this list and played with it a little and put a new twist on nids. Just two cents on a deceptively "out of date" codex:

Only things on the board to start is the flyrants which are virtually immune to small arms, and dominate combat. then the havoc begins, and your troops drop pod onto objectives and each have 3 wounds and can hold their own.
