Rapture is an incredibly unpredictable world. The simplest task, one that I’ve done dozens of times during the course of playing Bioshock (and games in general) can change dramatically given the slightest complication. The task at hand was securing a room. The complication? A security camera looking me square in the eyes.

The alarms sound, and within seconds security bots are swarming around me. I quickly survey the room. Two security bots, and two Splicers (the thugs of Rapture). I electrocute a security bot and stumble towards it. If I hack it, I might be able to turn this battle around. In my frazzled state I manage to botch up that routine job and I’m left in deeper trouble that I was already in. I’m losing health fast. I retreat, heal myself, and get back into the fray.

I’m still being attacked from all angles, but I hear something. A familiar, haunting moan. Slow, echoing footsteps. It could only be one thing: a Big Daddy. Normally it’s a sound that sends chills up my spine. But this time, I hear opportunity. A new plan is hatched. With a wry grin on my face, I select the “Hypnotize Big Daddy” plasmid and toss it at him. Now he’s on my side. I have half a mind to stay and watch the action unfold, but I’m shaken up and very low on health, so I dash out of the room. I don’t know exactly what happened, but when I re-entered moments later everything that moved was lying on the floor, charred or broken. Only the Big Daddy remained standing.

I’m tempted to kill him and steal his loot, but I can’t bring myself to do it. How am I suppose to kill the creature that just saved my life?
