HL2 novice here; I enjoy the game a lot. I hail from the city of Pittsburgh, home of the Super Bowl Champion Steelers. Quick question - I'm at the Water Hazard level, where the 2 APCs sit on the dock. I've destroyed the APCs, blown up the barrels inside the cargo container, and I am trying to jump the ramp (from under the dock, of course) to enter the tunnel. Every time I try, I crash into the ramp, no matter how far I back up. Is there something I'm missing here?
