It is 1939, a invasion of Poland by the Germans has begun! Defend Poland by using your rocket launcher to destroy the tanks that try to enter Poland. Each Blitzcreeg has more and more tanks to destroy. Make sure to destroy the bomb that passes by. Also, who is the legend who scored 15802900 I've only been able to get 1/4th of that. Absolute legend.
TIPS Use the Germans strategy against them, Concentration! Shoot the tanks, but concentrate all your power at the center of the blitzcreeg. The more tanks you destroy before the next blitzcreeg, the next wave will be easier than it would have.
