The other thing needed to go with them is a transport system, so sort of sorted that as well...
|Swarms plus transport.|
|4 swarms, 2 of each type. Should be enough(?)|
|Transport was bought a long time ago. Sadly, I only bought 3 of them so 1 short... Actually they're not models. They're pens I bought on the off-chance they would come in useful some day.|
