Gargantua (Half-Life)

The gargantua (Gargantuan Supreme Commander) is a large, blue alien creature from Half-Life.It is a kind of sub-boss creature and takes a large amount of explosive damage before getting destroyed. Gargantuas can be seen in Half-Life in the levels Power Up, Surface Tension, Interloper and Nihilanth. In most of these locations, there is a convenient arrangement for killing the gargantua so that one does not have to expend explosives on it.
