Tacticsoft is not giving anything, the one that gives 2.5 K extra is google play or Android ... but it isn´t Tacticsoft idea.
And regarding advertising for other games, have you seen a game called "War of Robots"? It´s a robot war similar to this we play, but the quality of 3D graphics is much better !!
I wonder why we are tied to this poor game and now it has also become monotonous and boring.
