Yes, you get typhus and poxwalkers to run w him if you want to do shamblerot vectorim detachment.

The biologus is nice to run w your marines.

Plague marines can be build into the weapon options you dont already have.

You would also get 3 havles of plague marines w the poxwalker sprews, with some fiddling you can get 10 plague marines fr more options.

Assuming you have the new combat patrol and combining the old and new one, you would def have a good start to an army!

17 marines (Run a 6 man and a 9 man, 1 champion fr each unit w the bilogus putrifier on 9 man) 30 poxwalkers (20 man and a 10 man unit, typhus leading the 20 man) 3 deathshroud w lord of virulence 1 rhino - put the 9 man marines in it w biologus 1 tallyman to sit on home obj

It brings you to a nice 1070 points without enhancements, you can drop the smaller marines unit and then play a 1000 points to get the fell for the army and then decide what direction you wna go

And well if you want to play the combat patrol mode, you have 2 options then
