Hello all.

I have reached the point where you link up with the Delta team marines and you fight your way to the Extraction point. When I arrive on location my blue dot updates telling me to help defend, but nothing happens. I see alien fire coming from a couple of box cars but no alients.

Also there is a human assault rifle floating mid air firing bursts of rounds at those box cars. No body attached.

I cannot advance past this point in the campaign due to bug. I reloaded my latest checkpoint and fought back to this point and it didn't help.

Anyone seen this?

Anyone?
