The easter eggs and secrets are many.
Cal, I challenge you to do something. Go back to the Tanker chapter, and
f**k around.Keep in mind when the game was released. Now do something like go behind the bar, and shoot at one of the bottles. Not only does it break and fall down, but it breaks
exactly where you shot it. You can even continue to shoot the glass bits, and they crack just like real life glass. Pans swing and clang exactly where you hit them. Shit flies around and falls with perfect physics.
Also, go in to one of the lockers with the hot chick poster. Now close it. Now duck. Now press look, and laugh as Snake leans forward and
kisses the poster.
That's just some of the tiny things that most people miss that make the game so great, and polished.
