Invasion!

Invasion was a series by Pat Mills (part one only) and Gerry Finley-Day which ran in 2000AD from issues #1-51 in 1977-78. It concerned truck driver turned resistance fighter Bill Savage's fight against the Volgans who had invaded Britain in 1990 and killed his family. The original series ended on an optimistic note with Savage believing that the Americans were about to liberate Britain, but the story was picked up in the series Savage in 2004 with the country still under the Volgan jackboot.
