bombarding sledge queen 

sledge queen gets bombed
STRATEGY:
you need at least 4 people to do this with either tickspider or blitzer (5 players is recommended, as it usually can kill SQ instantly)
spam tickspiders/blitzers in one area (until there's around 0:25 left on the timer) and have one person stay there as a bait
then lure the queen and bomb her, if she survives just beat her with remaining items
this strategy can be done night 1 if you get lucky timer (2:00 or above), otherwise just press 0 and hope you get a better one
however if you are unsure if it will work and kill her, you can always wait till night 2-3 and get extra explosives or guns.
