Sorry, but that is not at all.

Here historical battles are taken out of the Second World War as a base for a tower defense game in the style of Fieldrunners. To slaughter the evil German toy soldiers in droves only well-placed shooters are initially necessary. Later there then flamethrower, artillery, anti-aircraft guns and interceptors.

The first level block called Stalingrad. The only historical reference to be found in the white background, the well is intended to represent snow. The same is true for Operation Overlord (landing in France), Battle of Iwo Jima, and Operation Crusader (Africa Allied offensive). There each other backgrounds are displayed.
I think that's pretty tasteless and had something not expected from a game with toy soldiers. One could leave it without any harm to the game a form. On The Contrary.

Then here are In-App Purchases, as already described by other reviewers offered very pushy. I find that quite nonsensical in a tower defense game. This also Fieldrunners 2 had ruined for me.

Even the Strategic claim the one normally has in Tower Defense games is made by the In-App Purchases to naught. It's so that I either spend real money or get through enemy troops.

The developers clearly show with this game, such as micro-transactions destroy the whole game and how not to use historical references in games. As a school grade a smooth 6. Place.
