ikonius: I would very much like to skip the Lighthouse level as I am having a very hard time protecting the truck (my eyesignt isn't very good, even with the infrared scopes. the enemies are too small, even at max magnification).
OK, you are obviously past this now and don't care any more. But there are three Tips I would give for this sniper mission, which was VERY FRUSTRATING the first time I played Chaser and made me want to quit the game! But with these tips it will be a lot easier.
1. Use lots of Adrenaline mode. Watch the truck with your scope in zoomed-out (widest view) mode. Soon as you see a tiny gunman, center him in your scope, hit the Adrenaline key, and zoom in. Don't zoom in until you've centered on the gunman and triggered adrenaline. Place your crosshair just in front of where he's going to walk and wait for him to walk into your cursor and then pull the trigger. Be sure to exit Adrenaline immediately after the shot(s) to save it.
2. Stand as far to the right of the window as you can. The truck always moves left (or up/down) and you'll be able to stand at one window longer if you can pan to the left without the lefthand wall getting in your way.
3. Shoot the barrels BEHIND the guy with the grenade launcher. When you get to the street where the guy with the launcher is, don't bother to shoot him... shoot the barrels on the ground behind him. You'll need to be standing pretty far to the right of the window to see them (see tip #2). Not only will this kill the guy, but it will also blow up all the giant tanks on that street. If you DON'T explode the tanks before the truck rolls down that street, one of the other gunmen will trigger the explosions WHILE the truck is on that street, and the truck will take massive damage from the exploding tanks and you won't survive the mission. That's the biggest "secret" to this level that I found.
