A TPU regular recently suggested that the Battle of Britain map was unwinnable by the Axis. Certainly the TPU version of the map makes an Axis victory more difficult: the Allied factory and all five of the radar towers - all of which must be destroyed - respawn after a brief delay.
Still, I was certain that Axis victory was possible. But I was wrong. Checking TPU's map stats, I found that of the 854 rounds played on the BoB map, exactly zero had been won by the Axis.
Accordingly, I adjusted the map setup to make things easier for the Axis. The factory still respawns after a few minutes, but the radar towers do not.
It's not a squadron of Spitfires, but I think the Luftwaffe will find the going a bit easier now, in the skies over London.
