On May 14, last year, I started to develop this game. Actually, I had no idea about Unity by then or videogames development, so I just started to try things and eventually it turned out into something. In order to celebrate this, the game is on sale now for a week for just 0,99$ !
Also, there is a new version coming out soon, currently being tested. In this new version, WWII tanks will be replaced with a more modern tank:
As you can see, there is a gunner on the tank. Both the main turret and the gunner act independently: they can target different enemies. It will cost the same as the current tank, but it will take 3 ally slots instead of one.
The Übertank will also be replaced by this tank (but bigger).
There are other changes that will be revealed once the version is out!
