I like the idea of a grapple attack, perhaps you should make the grapple limited via only from the back.

Give the grapple a really small sort of 'hop' onto the enemies back to make it easier to target with.

Now for the marines, I've been thinking about possibly going into third person view when this happens and you press the USE key to lunge yourself backwards (of course aiming yourself for a wall first) to slam the skulk into a wall, popping it off and giving it a good bit of damage.

Although keeping it in first person mode with a sort of like... slime around your screen indicating that you've been grappled or something (plus staggering movements by your view) might be better so if you're assaulted by multiple skulks you can still defend yourself while you try to get the other one off.

Now being on the marine, I think the skulk should probobly take increased damage so that it dies if some other nearby marine shoots at it a couple times to get it off the marine. This makes it so that marines who travel away from the others are a more viable target for skulks and promote teamwork with the marines. Also: as the skulk grapples the damage should start out at a slow counter of damage per second and then slowly ramp up if the marine chooses to ignore the skulk as it bites through all the armor.

This whole situation is similar to L4D's hunter pounce except there are ways for both characters to continue controlling themselves afterward. (Perhaps after a few seconds of the skulk grappling someone they have the ability to leap off.)
