rules :
track the black and white target press left mouse to shoot,
keep in mind you have an ally to protect so when they appear on on the screen you have to protect them from the bullet the crosshair is shooting at them for extra points , be care full if you will miss hitting them you will lose charge .
and if we started talking about charge make sure the charge meter never gets below 0 or you will lose , if the bar gets to 90 or above you can rest it to gain more score .
