How to survive:
-Check all cupboards and find flashlight, electric box key and cable
-Go to the basement and open the electric box using your electric box key
-Retrieve two planks from the basement to barricade each window in the living room, kitchen, corridor and bedroom
-If the lights go off then dash to the basement while using your flashlight and then repair the electric box using a cable and then find another cable to after fixing the electric box -Remain in the living room for most of the time
-If you hear the garage door opening then dash to the garage and close the garage door
-If you hear something crawling in a vent then dash to the bathroom and close the vent once it opens
My strategy.
