You can pick them up immediately in PDF form from DriveThruRPG, and if you supported the original Kickstarter (back in 2013) you should receive a message from Modiphius enabling you to get them for free. (This may also apply to previous purchases of Achtung! Cthulhu in print and PDF – Modiphius will contact you.)
A "7th Edition" scenario, Under the Gun by Graeme Davis is also available.

The Secret War has begun!
