I'm in chapter 3. I've killed the 2 guardians. Now I need the Vortigaunt and Alex to follow me to the elevator, so the Vortigaunt can open the door.

However, the vortiguant stays put next to the thumper thingy. What do I do to get him to move to the gate?

Sorry, I meant to put this in the sandbox...

My bad....

Dude, this should be in the sandbox

Shouldn't you be re-assembling an engine???? OR sanding and buffing ????

I don't recall, it's been a few years since I played that game. Did you try kicking him in the balls? Search the web for a walk through or ask a 12 year old.
