The first Splicer type the player fights in the game, Thuggish Splicers are the bread and butter of BioShock combat, attacking the player with a battered melee weapon. Although easily dispatchable, they make up for this by being fast movers. There are two types of Thuggish Splicers; an ordinary variety (which also appears in BioShock 2) and an electrified variety that appears in later levels and is invulnerable to electrical attacks. The electrified variant also take a lot more ammo to kill, since Electro Bolt will no longer have any effect on them. In BioShock 2, Thuggish Splicers only appear in the first four levels.
