I got the "game" but the only thing i have is an empty world whoch 3 white boxes to shoot and 4 crates so did i need sometrhing else?

No, you got the right thing. That was just a foretaste, basically showing the new crosshairs and boxes to shoot.

so is there at all any map other than that?

The next update will feature a map with that building shown.
