"alternate-history" tower-defense game involving plenty of tanks which just got a lot more WW2 themed.
The plot of Gratuitous Tank Battles is that the first World War kinda never ended, but got lasers! Now The Western Front pushes it into WW2 as Yanks face the Krauts in Europe through 8 missions.
There are also 16 new tank hulls to choose from, which can be used in the original game. The first four maps are WW2 tech only, but the others are open to laser Tiger tanks.
It can be purchased directly from theor through Steam shortly.
