Dynamite has been installed around his feet, and Adrian Shephard must quickly detonates it in order to destroy the creature. In Opposing Force, a Gargantua can be seen tied up on top of the Hydro-Electric Dam (If not defeated fast enough, it will break loose and the player must find a way to outrun it), in the chapter Foxtrot Uniform, while HECU soldiers and Shock Troopers fight around and against it. The last time the Gargantua appears in Half-Life is in the chapter Nihilanth: when being teleported by the Nihilanth in the third chamber for the fourth time, a Gargantua appears instead of Alien Controllers.Ī Gargantua also appears during the final sequence of the Uplink, where it kills several Black Mesa employees while the G-Man watches, before slowly heading towards the cornered player, at which point the demo ends. The Gargantua is next seen on Xen (in what may be its natural habitat) during the chapter Interloper, where it can simply be avoided or destroyed by luring it near the Xen trees. Upon noticing Freeman, it chases him in a tunnel leading to Waste Processing Area 3, where Freeman has to use a Tactical Map set up by the HECU to destroy it with airstrikes It is seen again in the chapter Surface Tension, where it throws Black Mesa SUVs at HECU soldiers in an underground parking lot of the Topside Motorpool, leading to the Waste Processing Area 3. Two HECU soldiers fighting a Gargantua in Sector E Track Control. To defeat it, Freeman has to bring back power to the tracks leading to the Sector E Materials Transport network and the small power station located nearby, where the creature will be destroyed by electric discharges. There it is fighting against two HECU soldiers while the G-Man is watching from the control room, and soon turns to Gordon Freeman upon noticing him. It is first introduced in Sector E Track Control during the Half-Life chapter Power Up. It is unknown if the Gargantua is a natural species or if it is manufactured like the Alien Grunt, though its integrated weaponry and bio-mechanical appearance suggest that it is an artificially engineered monster. It requires a large amount of explosive, electrical, or energy damage before being destroyed and it can rarely be defeated with conventional methods. The creature has a thick shell or carapace that renders it completely bulletproof. Instead of hands, it sports two massive pincers that can be opened to emit jets of intense heat (the Alien Grunt hands are also similar), as well as a pair of vestigial legs below the trunk, a common trait in most bipedal Xen creatures. The Gargantua is approximately six meters (20 feet) tall, mostly blue in color, and has one yellow eye that glows red when it perceives a hostile unit.
