Houdini Splicers are a unique kind of Splicer, as they are one of the few types known to be capable of using offensive Plasmids while possessing the ability to turn into an invisible cloud of molecules and reform elsewhere. There are two types of Houdini Splicers: ordinary fire-wielding Houdini Splicers who appear in BioShock, BioShock 2 and BioShock Infinite's downloadable content, Burial at Sea - Episode 2, and ice-wielding Houdinis who are much stronger and appear in the later levels of the first game and in BioShock 2's downloadable content, Minerva's Den. Additionally, a non-hostile variant using both fire and ice-based Plasmids appears briefly in Burial at Sea - Episode 1.
