Also When you buy bowie knife USE it. It is one hit kill up to 12 wave, but i cant seem to buy it before 9 wave. also when insta kill is active use weaker weapon and try to use knife as much as you can. Also use knife if you have both insta kill and double points active, since that method will give you large amounts for points. Also try to get to generator room from left side since you will unlock less doors and thompson is great weapon for early rounds.
