In general this scenario is going to put the player in the situation of Churchill. The big goal in this scenario will be for the player to resist against the Axis Invasion of Europe until the entrance of the USA in the war which gonna give you new technologies and units supplements but it's not going to be an easy task. But when the USA will join you, it will be far from over because the Nazi will have some big defense left all around the Europe and the player will have to be fast in defeating the Nazi War Machine of they going to have some really big technologies like the jet figther or jet bomber or the NUCLEAR BOMB which going to be a big advantage for them.
