Pokemon Apocalypse

It's been 5 months since it began, the apocalypse. 1/4 of the population has been slaughter and the rate of it grows. You've been hiding alone in a loft that went unnoticed during the initial attack on the city you're in. But you still hear Pokemon occasionally outside and have to stay on alert.

It's another day, you'll have to go out for resources (mainly food), but as you begin walking out of your hiding spot, you heard the door creak open with footsteps coming in. What do you do?
