The second set of downloadable content for 2K Games’ excellent first-person shooter/adventure game, Bioshock 2, becomes available today on the US PlayStation Store for $9.99.

This next DLC pack for Bioshock 2’s multiplayer mode, known as the Rapture Metro DLC pack, will include six new maps from Rapture’s history, “many of them offering a distinctly different tactical focus than the original set” that was shipped with Bioshock 2.

It will also include three new Trophies and a new ‘Rebirth’ feature, which will enable players to ‘rank down’ to Level 1 once they have reached Level 50, thereby earning a special Golden Bunny mask and a prestigious indicator next to their name to taunt others. Players who make it back to 50 again will earn the Golden Bucket, which will tell the world that “you’re so damn good you don’t have to care.”

The Rapture Metro DLC pack will be released alongside the free Kill ‘em Kindly downloadable mode, which is also multiplayer-focused. According to Jordan Thomas, Creative Director at 2K Marin, Kill ‘em Kindly is a “melee-only game” that’s “all about stalking the dripping halls with a golf club and looking for prey — and then bludgeoning all & sundry to death. You might also offer a pithy quip of some kind, espousing your personal philosophy to the sub-human lump of gristle who had the temerity to face you on the field of battle. It’s entirely up to you.”

You can enjoy some of the melee action from the Kill ‘em Kindly mode below and find out more details about the six new maps from the Rapture Metro DLC pack after that.

• Pauper’s Drop: The Hooverville-like shanty which sprang up during the construction of the Atlantic Express. With long sightlines and open courtyards at the center, the Drop opens up opportunities for honest-to-gosh sniping in a way that our release maps weren’t as focused around.

• Dionysus Park: The single best example of the gleaming, Utopia-in-peril setting of the BioShock Multiplayer experience, Dionysus Park is an art gallery owned by Sofia Lamb. It appeared in the BioShock 2 single player component as a filth-encrusted, recently flooded garden of goop. But here in 1959, all that pain and decay have been peeled away, and it can be enjoyed in its original, golden splendor. Territory and security control feature prominently in the park’s tactical terrain.

• Fontaine Fisheries: A key location from the original BioShock, the Fisheries were home to Fontaine and his gangland allies. It’s symmetrical in nature, with the icy freezers as the center of conflict. You’ll battle through dock areas, salt ponds, and more as you make shady new friends and then gut them like fish.

• Fighting McDonagh’s: This is a zoomed-in, intimate look at one of the Fisheries’ most famous locations. The Fighting McDonagh’s tavern was the favored watering hole of the city’s underclass, who took the frustration of their broken utopian dreams out on each other in sponsored boxing matches. It’s dense and highly interconnected, serving up plenty of chances for a close-range ambush.

• Smuggler’s Hideout: This cavernous, once-secret location was where Fontaine’s smuggling operation docked a private submarine and moved contraband into Rapture, daring Andrew Ryan to stop the people getting what they wanted. The bulk of it favors long range skirmishing, but it has a number of back routes and semi-secret tunnels to help you sneak up on snipers and ventilate ‘em.

• Siren Alley: Shaped like a big, sexy donut, Siren Alley was the red-light district in Rapture. The looping path means it’s easy to find the action, and the footbridges and overlooks allow you to snipe from higher ground. Shortcuts through the interior flophouses give you a chance to bushwhack someone whether they take the high road or the low.
