Klam,
I'm running a system that can barely handle this game at low settings.
What I've learned is that you need to follow the concrete, and they will eventualy lead to a bridge.
Use the "Z" button and zoom in on the places you want to go. This helps me set a route to the destination.
Pay special attention to the gun rotation numbers in the top left.
I tend to watch my clipboard map to make sure I'm headed in the right direction.
Once you get across the bridge, be ruthless. Move fast and set up a nice ambush spot.
Shut down and start shelling. Hold the beach-head at all costs.
If you hear a whistling noise, don't look up.
