Puesto que nadie ha recibido el juego con la hidra (los tentáculos azules), solo nos podemos guiar por lo que dijo Valve:
"Half life - raising the bar"
The Hydra was made of luminous gelatenous flesh, with organs that are clearly visible. The visible head was part of a larger, massive colonial organism.
"The hydra was my pet feature, a monster I wanted in from the start. We designed whole areas of the game around it. I personally spent about six months on and off getting all the movement algorithims and physics for it in a working state. Everyone was pretty skeptical it was even possible when I started, so I kept it pretty low profile , but once i got some of the early rough AI drafts up and running, people would sneak one on to a map, check it out, and get all excited, and start pushing me to hurry up and finish it. However, the closer it got to being done, the more its fatal flaw was becoming clear: it was amazingly cool to watch it fight other characters, but it was zero fun to play against in first person. When it attacked others, as the player you could see this great big glowing giant worm snaking through the map, knocking stuff over and putting on a great show, but when it attacked you, you'd just see this nondescript blob doing something vague, then you'd be dead. Cutting it was personally very painful, but I had to do it, when a design just isn't working, it just isn't working. I'd still like to see this in the Half-Life universe somewhere, maybe rethink its AI more along the lines of an Antlion.
