BioShock 2 Enemies

Subject Delta battles many enemies in BioShock 2, including Splicers, other Big Daddies, and other mysterious adversaries found in Rapture's depths.

Big Daddy


Big Daddies escort Little Sisters on their ADAM extraction missions throughout Rapture, and are formidable adversaries when angered. In addition to Bouncers and Rosies, the Rumbler is the third Big Daddy enemy type encountered in the game. They fire Heat-Seeking RPGs from a shoulder-mounted cannon and deploy small automated turrets.

Big Sisters


The Big Sisters are described as Little Sisters who has trouble adapting to Rapture's environment upon reaching adolescence, and have become unstable. They have the appearance of a thin, feminine version of Big Daddies, possessing very similar metallic equipment. There are cages on their backs which are used to carry Little Sisters. When the player incurs their wrath, their red eye will be glowing on the front of their helmets, and then the Big Sisters spring into motion. They have a large ADAM needle on their left arms, which is used for precision melee attacks and to drain ADAM from victims. They are able to jump across an entire room, have immense strength and agility, and possess powerful plasmids.

Little Sister


Little Sisters still wander the halls of Rapture, extracting ADAM from corpses while being watched over by Big Daddies, and in some cases, Big Sisters. As the prototype Big Daddy, Subject Delta has the option of adopting a Little Sister, who shares some of the ADAM she extracts as she is protected from Splicers.

Splicer


Among the previously encountered Splicer types, Brute Splicers make their appearance as enemies. Large, hulking humanoid beings, Brute Splicers have lost much of their human appearance due to years of gene splicing. They have a considerable strength in melee attacks, and are strong enough to hurl large objects, causing heavy damage. They can also take a severe amount of punishment before succumbing to death.

Rapture Security
Security Bots, Security Cameras, and Turrets will be making a return. A new type of turret has been confirmed, and it is a smaller, portable kind that can be carried around (See Miniature Turret). They are also used as weapons by the Rumbler Big Daddy.
