step 1: reinforce random walls
step 2: go to window that leads to outside (preferably where other team spawns)
step 3: place turret
step 4: wait for preparation phase to end (much preferred if drone doesnt see you)
step 5: here you will either
a. kill 1-5 people depending on how much spawned
b. kill no one.
if a happens then u did this guide successfully
if b happens do step 1-5 again next round
