Who's your Daddy?

Three Challenge Rooms, 2 of them involve going head to head with Big Daddies.

+A Shocking Turn of Events: A Little Sister is trapped atop a Ferris wheel. Players must create electricity to power the Ferris wheel and bring the Little Sister to safety.
+The I in Team: Using limited resources, and an even more limited arsenal, players must negotiate traps and find a way to defeat a Big Daddy.
+Worlds of Hurt: Players must battle through eight rooms of Big Daddies, Splicers and the worst that Rapture has to offer. Accumulate Adam, build an arsenal of Plasmids, Tonics and Weaponry, and fight through to rescue the Little Sister.
