Plasmids are special serums made from processed ADAM that introduce modified stem cells into the body, allowing for genetic modification and mutation, giving the user what some might call "super powers". In BioShock 2 Multiplayer, Plasmids and weapons are wielded somewhat simultaneously in that the player holds the weapon with two hands, but can quickly cast a Plasmid without have to switch. Only three Plasmids, Electro Bolt, Incinerate! and Winter Blast are available when a player first starts. The rest of the Plasmids are unlocked as the player advances through the Ranks.
