Not much into multiplayer? Try the BioShock 2 single-player DLC, then. Today, the 'Protector Trials' add-on is released to PSN and the Xbox LIVE Marketplace, for $4.99 and 400 Microsoft Points -- respectively.
You're plopped into the boots of the Big Daddy as he kills off Splicers to protect his Little Sister. As the first single-player DLC, Protector Trials adds the following to BioShock 2:
- Six new maps: three unique difficulty levels, each based on favorite locales from BioShock 2;
- New unlockables, including never-before-seen concept art and videos;
- Seven new Achievements/Trophies.
Expect more to come.
