When using the backlash when you find one you have a very strong advantage of the stalker. What you do is don`t get shot but you take the backlash and throw it on the ground in front of the stalker. Then when it tries to shoot you it will take there fire and use it aganst them buy using the special power it will soon destroy it self. But there is one diadvantage the backlash does not return missles back to them because that is a bigger bullet to turn around. It is also a short 20 second sheild so as soon as it goes down throw one more f you have one or run if you don`t and wait for it to turn around to something els and shoot it`s power core in th back of the stalker. I hope thi will help you!
