The '''Barnacle Grapple''', also known as '''Specimen 1176''', is a detached Barnacle which can be used as both a weapon and a grappling hook. Its tongue can be shot out to latch onto organic objects, such as enemies.


The Barnacle Grapple is most useful for latching onto Spore Launcher spores attached to Race X moss, occasionally bearing ammunition for the Spore Launcher weapon, and pulling the player to otherwise inaccessible places. It is also useful as a handy melee tool to devour Standard Headcrab|Headcrabs and Shock Roaches. 

The weapon's secondary trigger makes the Barnacle keep its tongue out to let its user come down with less or no injury. 

When latching to a larger creature, the user will be pulled along with the gun instead of the creature pulled towards the user, but may nonetheless be eaten the same way as smaller enemies. 

===''Half-Life Opposing Force''===

In ''Opposing Force'', it is learned that the Black Mesa Science Team|Black Mesa scientists working in Sector E's Biodome Complex have been able to successfully detach a Barnacle (named "Specimen 1176") from its point of gestation, in good health, and were able to coerce it into latching onto organic materials, such as creatures, fungi and moss, and convert it as a portable weapon. 

After hearing in the Specimen Testing Lab within the Biodome Complex a holographic message from a scientist to Walter Bennet explaining the work achieved on Specimen 1176, Adrian Shephard proceeds to the Specimen Containment Room where the creature can be found in a case near other Xen flora specimen in other cases, and equips the unique creature as a weapon. He then can test the weapon in Testing Lab BDRC-101 on several things a Headcrab, a Houndeye and a crate and rocks, the latter being there to show the weapon's inefficiency against non-organic materials. In the Specimen Cultivation Rooms nearby it is also learned how to use the Barnacle Gun on Spore Launcher spores to cross deep pits.

Shephard then carries the gun with him on his quest through Black Mesa until finally reaching the Gene Worm, against which the weapon is instrumental in defeating the creature, as it helps bridging a gap to reach the second of the two cannons Shephard uses to defeat the creature.
