9lives.be: "M.E. Chung, Multiplayer Designer at 2K Marin, revealed some new multiplayer modes for BioShock 2.
The first mode is Turf War. It's a faction-based mode where you have to gain control of Rapture's territories to win the game. You gain control by finding specific points within the map that control the territories, your proximity to the control point will fill up a meter and gain control of the point for your team when its full. The faction that has held onto the spaces the longest will prevail.
The second one is called ADAM Grab. It's a mode where your possession of the Little Sister gives you ADAM, and the person who holds onto her the longest will win the game. It was a challenge coming up with rules that fit because of the way the cities were designed. We wanted to find something that worked with the strengths of Rapture's architecture, so that's where ADAM Grab comes in – the point is to get the Little Sister and to get "lost" in the city.
Finally, Last Splicer Standing is a variant on the already announced Civil War mode. There's no respawning in this mode like the other ones; it's a round-based mode where each round's winner is determined when everyone on the other team is down. Taking respawn out and putting all the value of survivability on one life changed the pace of the game. We liked that it was a different experience, so we kept it in as a variant for people who really enjoy the slower, more deliberate-action style of gameplay."
