BioShock 2: The Protector Trials

The Protector Trials is the third DLC for BioShock 2 and the first to expand the singleplayer mode. Players step into the role of a Big Daddy who must fight off splicers while his Little Sister harvests ADAM from corpses. It offers six new maps with three difficulty levels (each based on locales from BioShock 2), new unlockables, including concept art and videos, as well as seven new achievements/trophies. There are three new weapons and Plasmid load-outs plus a fourth bonus load-out received when all previous ones are completed.
