toy defense 2 battle of stalingrad level 15 tanks too close together

For instance once you unlock say flamethrowers and rocket launchers in the upgrade tree, then in game you can upgrade your soldier unit to either a flamethrower or a rocket launcher. I sort of wish that through the upgrade system those base units would be transformed into better quality units or even a branch off upgrade system akin to Kingdom Rush. This can really be a hassle in money management especially when the prices seem disproportionate and you are faced with an air attack the second wave. For instance you have two types which only can attack air units and one that can only attack land (soldiers can attack both).

While it seems that keeping tower types at a simple number I do feel Toy Defense 2 lacks some variety even with the nice upgrade system. The actual upgrades are very detailed and offer some unique advantages such as deploying Czech Hedgehogs and various militant technology which increases damage, accuracy, etc. Each of these can be upgraded outside of battle into a very nice split upgrade tree and then can be upgraded in game. Unit types are kept to a succinct four types: soldiers, planes (interceptors), artillery and ack-acks.

As to be expected Toy Defense 2 takes on the role of portraying these vital World War 2 battles into cutesy bite sized app chunks but for what it is worth Toy Defense 2 does do a good job at keeping the tower defense sub-genre fresh without getting overly complicated.
