Doom 3....How do I win in Hell ??

[sirlancelotsd]

I have been fighting that huge monster in Hell but am not making any progress. What am I missing? How do I kill that thing?

[ergar...O!!! >:v]

U have to kill the monsters that spawn in the center so u can charge the "cube of souls", i think that is its name, once charged use the cube of souls against the ciberdemon, repeat until its defeated.

If you mean the "boss" monster thing in Hell itself, the big..uhh.."dog" or whatever(lol):

Shoot down those seekers flying around, they are essentially the boss`s eyes and ears, when you have shot down all, the boss will "open up" a part on his back to spawn more, and he then becomes vulnerable to damage. He is only vulnerable for a few moments though, before spawning new seekers and "closing up", just keep shooting them down, when he opens up, shoot him, rince and repeat :)

You must be referring to the Guardian of Hell. Shoot a few of the flying seekers and when you shoot down enough, the Guardian will spawn more from the blue orb that appears above him. Shoot the blue orb, you'll notice it turning red when you damage it.

Thanks for all your help. I did finally defeat him. Now if I only could kill the final monster down in the excavation site.

The final monster is only hurt via soul cube, remember that
