Hello Dawg, the links to download are in the opening post.
What I've done is to have put them into Blitz Scenario DB with long titles such as "Ode to Panzerblitz: Scenario 1 (MCS 2.02)", so to be able to find them all,
- Go to Scenarios -> Search scenarios
- Select -> Ladder: Campaign Series
- Perhaps select no game at all
- Title: type in: (MCS 2.02)
- Author: type in: Arvold
Hit Search, and you should see the complete listing of all scenarios uploaded there so far.
There's like three pages of them already
