Species Location Weapon Abilities The double lurker is a team of enemies in The Precursor Legacy. There are two types of blue-tinted lurkers which comprise the duo lurkers, the two of which have very similar traits, though one being smaller than the other, and—as a consequence—pair up together with one on top of the other to provide a larger, stronger enemy. The bottom lurker cannot be defeated unless the top lurker is knocked off his shoulders. This can be done by jumping and kicking (+). Once the two are separated each can be destroyed with one melee attack.
