Gargantua

Gargantua's History

The Gargantua is a large and powerful species of Xen alien featured in Half-Life, Half-Life: Uplink, and Half-Life: Opposing Force.

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. 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,[1] a common trait in most bipedal Xen creatures.

The creature has a thick shell or carapace that renders it completely bulletproof. It requires a large amount of explosive, electrical, or energy damage before being destroyed and it can rarely be defeated with conventional methods.

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.
