This destroys the grid and allows you to continue. Some of the puzzles can occasionally seem a bit tricky, but I believe this is largely because the Japanese version of the game contains no English dialogue. The level design is really excellent throughout Metal Gear Solid . The excellent atmosphere the game generates enhances the gaming experience even further. The music is spot on, changing from cautious to pacey depending on the current scene.
Sound effects are excellent, with realistic gun shots, footsteps, explosions, and more.
Graphical touches also enhance the game's atmosphere. Papers fly off a desk as you throw an opponent against it, there's ripples in the puddles, reflections in polished floors, driving snow outside, and Snake even leaves footprints in the fresh snow. The attention to detail in this game is astounding. For example, mid-way through the game Snake is imprisoned and catches a cold. From this point onwards he occasionally sneezes, and this sound will bring nearby guards towards you as they attempt to investigate.
