I'm told to take out the Hand, Refinery, and open the gate. None of which I can do.

The Hand and Refinery repair themselves faster than I can damage them with any weapon. The gate switch does nothing. This isn't the first glitch I've encountered, but it is the worst.

Anyone have any advice? Something obvious I'm missing (prob with the gate--it won't open until the buildings are down?). Wait for a patch?

I have tried restarting the mission a dozen or so times.

Thanks.
