So I've been thinking: 'Nid swarm armies are pretty much a thing of the past. It's simply not cost effective. That gave me an idea.
Giving the 'Nids a one point model, called a Swarmling.
The stat line I was considering:
WS 1, BS 0, S 2, T 2, I 1, W 1, A 1, Ld 5, Sv -
Infiltrate, Unending swarm, Fragile, Instinctive behavior (feed) (plus any other standard 'nid rules)
Squad size 20-50.
Unending swarm: When a unit of Swarmlings is completely destroyed, another unit of equal size enters ongoing reserves.
Fragile: Almost any blow that connects with a Swarmling is likely to be lethal. All failed wounds against Swarmlings must be rerolled.
Thoughts?
