You were at a high school party hosted by your friend, you were having the time of your life before the lights shut off, you hear a noise, the lights turn back on and you see your friend dead, a knife through their forehead

"looks like I missed one." the voice said looking at you with his mischievous smirk, a gun in his right hand

"You have 20 seconds to run." he laughed and gave you a head start, you should start running by now..
