Bioshock 2: Fall of rapture (multiplayer)

BioShock 2 features a story-driven multiplayer mode in which the player takes on the role of a citizen of Rapture. Set in 1959, just before the events of BioShock, the player chooses to take on the role of a splicer fighting in Rapture's civil war. The player is being sponsored by the plasmid manufacturer, Sinclair Solutions, to test out their weapons, plasmids, and Tonics in a consumer reward program. As the player progresses through the multiplayer experience, new weapons, tonics, and plasmids will be unlocked (provided by Sinclair) in addition to the story of the Rapture civil war being told.
The player can choose from among 6 characters to serve as an in-game avatar. The characters are: Jacob Norris the welder, Barbara Johnson the housewife, Danny Wilkins the football star, Buck Raleigh the businessman, Naledi Atkins the pilot, and Suresh Sheti the Indian mystic. Two additional characters were available as a pre-order bonus from 12game, GameStop,EB games or Game, or through the purchase of a DLC pack: a fisherman named Zigo d'Acosta and an actress named Mille Blanche de Glace. Another two characters were made available by downloading the Sinclair Solutions Tester Pack: a criminal named Louie McGraff and a smooth-talking playboy named Oscar Calraca.
Multiplayer comes in 7 different modes, two of which have a single-player and team-based mode. The modes are:

Survival of the Fittest

A 'free-for-all' mode in which each player gets points for killing each of the other players. Whichever player accumulated the most kills or 20 kills by the end of the match wins.

Civil War

Players are divided into two opposing teams, and the team with the most collective kills of members of the other team at the end of the match wins.

Last Splicer Standing

A variation of 'Civil War' in which players do not respawn after being killed; each match consists of several rounds in which players attempt to outlive the players on the enemy team.

Capture the Sister

A 'Capture the Flag'-style mode in which players are divided into two teams, one of which must protect a Little Sister while the other tries to steal her and place her in a vent on the other side of the map. The team protecting the Little Sister will have a randomly chosen player to be a Big Daddy. After a predetermined amount of time, the teams switch roles. Whichever team has the most captures at the end of the match wins.

ADAM Grab

In this mode there is one Little Sister on the map and the player must seek her out and maintain possession of her as long as possible. The first person to hold onto the Little Sister for 3 minutes wins.

Team ADAM Grab

A variant of 'ADAM Grab' in which players are divided into two teams. The objective is the same, but victory is determined by a collective score rather than individual scores, and the first team to hold the Little Sister for 3 minutes wins.

Turf War

Players are split into two teams and each team must reach a number of predetermined points on the map to capture that point. The team with the most control points over the longest time wins.

In the multiplayer modes 'Survival of the Fittest', 'Civil War', and 'Turf War', a Big Daddy suit will spawn at a random location in the level. The choice is given to the player who finds this suit to become the Big Daddy, which will give the player greater strength and endurance but prohibits the use of plasmids and hacking, as well as expelling any previously held damage bonuses against other players. The Big Daddy can stomp, shoot a rivet gun, melee attack, and throw proximity mines. All damage dealt to the Big Daddy is permanent, and cannot be replenished. Once the Big Daddy is defeated, the suit disappears and spawns in another location on the map two minutes later. In 'Capture the Sister' one member of the defending team is chosen at random to be the Big Daddy; after the player's death, the Big Daddy suit disappears for the rest of the round.
