level boss help

Please help i am stuck with opposing force.
I am against a level boss i have schot his both eyes but dont no wat to do next.
i am playing this level two days now.
It is making me crazy

Shoot this main boss in the eye with the laser guns and then his belly will open up with a pink warp looking thing. Shoot that with a big gun and he will send out a teleport guy to attack you. After first time the bridge is out so use the barnacle creature to get across to the other laser. Repeat process and try not to die to be game. Good Luck,

Any questions lemme know.

I'm on the boss level also,I must have gone
though the shooting of the eyes and belly 30 times if not once!!!
what does it take to kill this Worm????

30 times?OMG,default is 4.All i knows finished it after killing it 4 times.
Did u shoot BOTH his eyes with the laser guns,shot the pink belly until he went all mad and spitted out a creature?Oh try this:
Shoot the belly with M-249 SAW Light machine gun.(the most powerful machine gun,its number 6)If it still dont works than its a shame.I still havent finished Ninilanth cuz it wont die.Just like what is happening here.1 question about ninilanth....When i shot the crystals do i have to shoor his head so it will open?then shoot his brain?
