Easiest way to get points: stay on the railroad
track on the left side the entire time, and as
soon as monsters start running at you, just back
up (stay on the track) and they'll all come at
you in the same line.
stay to the railroad track on the left and keep
your weapon aimed upwards, the enemies will come
to you and directly in your line of fire. using
the crowbar gives you the most points, and if you
decide to use the gun blowup the orange things,
they're oil canisters and they slaughter
everything around them.
