I'm here Predator! How can I help you?
Glad to see your enthusiasm for MC-SE. I'm playtesting it through now and I KNOW you won't be disappointed.
The other MC's are available as downloads, except for Watchtower, which you can still buy on a CD. I think you can get the others on CD too, but it is a little extra.
They should be listed in the products section here at Matrix.
