This was one of the best games every when you could play in on a PC through Facebook, but now I googled (searched) for the game and it told me to install it through BlueStacks, so no problem I have that and opened the game. But, how do you move the rifle and fire? Does this have to be on a touch screen like an I-Pad? It's impossible to play through such a small screen, so we need to be able to use the mouse, or even a game controller, to move the rifle and fire. Is that going to be a problem?
