TooFatLardies have released a reworked version of their Operation Sea Lion scenario booklet.
From their website:
Operation Sea Lion is 74 pages long (the original was only 43 pages) and contains 14 scenarios that stretch across the southern counties of England. Additionally there is an historical section that introduces the German invasion plans and the British defensive arrangements. There is also an account of the results of the 1974 game presented on a day by day basis for those wishing to find out what happened in that classic wargame.
Operation Sea Lion is available as a pdf download, designed for minimum ink usage, with each scenario ready to be printed out and played, all for just £8.
Check out their blog for the full details of the development of this book.
