Barnacle Gun
The fan-favorite from Opposing Force is back, in new form. Your very own pet barnacle.
The Barnacle gun functions as a grappling hook, allowing you to latch on to almost any surface or object and pull you along. Physics enabled objects (unfortunately not infected) will be pulled toward you instead. Use the reload or alt-fire key while firing to safely rappel down.
Note: Not compatible with some other heavily scripted mods. Only available in the official campaigns.
