I'm in the level "Gods and Monsters" and got to the Alpha Ceph but... nothing happens.
Actually, it looks like he isn't even there. That's right, the final boss fight and the boss is AWOL!

This level has been buggy from the start with Prophet constantly repeating certain phrases.

I reinstalled the game to no avail. I also have no anti-virus running.
So far I've come down to deleting the game saves for this level and playing back to this point
to see what happens.

Anyone else had issues like this?
