System Shock 2 begins with you being unfrozen from a long cryogenic sleep aboard the Rickenbacker, a security spaceship assigned to tail the Von Braun on her maiden voyage. Apparently, the Von Braun has been infested by an unknown alien race and has converted the crew into relatively intelligent zombies. You must gather bits of audio clips along the way to figure out what happened to your crew and, more importantly, how you can rid the ship of the aliens. Rely on your skills training from either the Navy, Marines, or OSA to guide you on this difficult path. This 3D title offers unbelievable graphics, as the Thief engine is utilized to provide mouth-watering environments and character skins. The astounding graphics, varied RPG elements, and fluid action make this title worthwhile.
FPS, RPG, Sci-fi and survival all combined in a very good game. The magic thing is that these are combined, but are still as complete as in a pure FPS, a pure RPG or a pure survival game.
e.g. the RPG part of this game is even better than the one in Deus Ex, with possible upgrades on weapons and technical abilities, characteristics and all the psionic powers that can be compared to magic spells. You also have to identify items and of course to hack many systems.
The excellent atmosphere is the other top point of the game (think Alien). You really feel uncomfortable, nervous, claustrophobic. Also, the storyline being introduced via recordings that you'll find here and there is perfect.
But there are several bad points, the most important one being the enemies respawn system. In some places, enemies respawn at about 10 meters from you, 10 seconds after the previous enemy is killed, and no good reason is provided for that to happen. Pretty boring, and pretty bad way to increase the game duration IMO. Also, the two last fights are not that hard, once you know how to do them.
Still, a must-play for Deus Ex, Bioshock, Alien movies or Half-Life (especially the 1st) lovers.
