So actually you want the grunt as a cinematic scene?

What Frictional Games did was spawning the grunt, giving it some pathnodes, and then it's up to the player, what's gonna happen.

I'm pretty sure they made the pathnodes like this:
3 main points: A - B - C

A:
Where the grunt spawns.
Maybe it has a little wait time before it goes...

B: A place somewhere close. An open place. Could be a crossway. Here it waits a bit. Then it proceeds to...

C:
The ending, where the player will not be, and where it disappears without the player noticing.


They're not really meant for being controlled. They're meant for walking from point A to C, while looking for the player.
