Two new pieces of single player DLC for Bioshock 2 are coming to PSN, Games for Windows and XBL later this year, 2K Games revealed today.

The first installment is the “Protector Trials” pack, which features six maps based on  existing environments in which one defends a little sister from splicers, like in the story.

The hook to the pack is the three “unique” difficulty modes, which the announcement promises will “push players’ mastery of weapons and Plasmids”, in addition to “never-before-seen” concept art.

Also announced was new story content, which would provide players with “new tools” and “extend the lore and fiction of the failed utopia under the sea”.

The “Protector Trials” is slated for release on August 3rd, while the narrative content is to come within in the coming months.
