metal gear solid 2 : sons of liberty
but there is a much wider range of skills offered to the player rather than just sneak and shoot. The new first-person aiming mode allows players to target specific things with there gun, (like an enemies head) greatly expanding tactical options. guards could be blinded by steam by shooting pipes, or hit in key weak spots, such as radios which disables the enemy from requesting "back-up" and the head; which would result in an instant death or the soldier being put to sleep immediately, depending on whether the player was using a gun or a tranquilizer.
Players can now walk slowly, allowing them to sneak over noisy flooring without making a sound, or hang off ledges to slip past below guards' feet. The corner-press move from the original title, which allowed players a sneak-peak around the next bend, was expanded to allow players to fire around edges from cover.
In the newest installment, the antagonist guards were given more advanced AI "to prevent an imbalance of power", and unlike the original Metal Gear Solid, work in squads. This amounts to them calling on their radios for a strike team upon seeing your character, then attempting to flank him and cut off his escape while avoiding the player's attacks. Often strike teams will carry body armor and riot shields, making them an even greater threat to the player. Even if the player escapes to some hiding place like a locker or vent, a Clearing team will sweep in to check the area, often blowing the player's cover and causing another dangerous chase to safety.
This all makes for an extremely enjoyable experiance and opens a window for gamers to either sneak through the game trying to stay undetected, using tranquilizer guns and silencers for your weapons, hiding bodies in lockers and yourself in boxes. You can also go all guns blazing and blast your way through parts of the game bringing out assult rifiles, rocket launchers and sniper rifels.
Its deffinatly worth playing and has recieved good response from most gamers around the world. some feel the lengthy dialogue disrupted the gameplay and slowed it down to much but still made the game a great addition to the playstation universe.
