I wait until I get the alert that I'm no longer in a safe zone. My eyes wander, tracing the cracks in the tiled walls, examining the mouldering toilet. I might look like I'm camping, crouched in the corner with my shotgun pointed at the door, but this isn't about taking advantage of unsuspecting prey-it's about survival. I've been hiding in the bathroom for the past five minutes now, an eternity in game time.
