EuroGamer - Serious Sam has one trick. It's simple, but effective. First it puts a big shiny thing in front of you. "Check this out, Dicky-boy, it's a COLLECTIBLE!" You pick it up, and immediately a hundred monsters spawn around the plinth. You either emerge like Bruce Campbell clutching your prize between clenched butt-cheeks, or reload and pick up the shiny thing again in all innocence. And then, a little way on, you find another shiny thing.
