I recently pulled this game out of my “old games” draw, and I have to say, its probrably the most fun i’ve had for a while in any game recently. While the graphics suck, the gameplay is very good, and the atmosphere is incredible - it still retains its scare factor today, even with it’s low end technology and graphical capabilities.
Its a bit of a bitch to get running on newer operating systems, but it is well worth it. It is one of the most atmospheric experiences you can have with a game - the combination of excellent sound design and constant survival aspect make this game incredibly eerie to play.
Bioshock has been recognised as sytem shock 2’s successor, except System Shock 2 has far deeper gameplay in many areas (hacking, character development, and psi skills/plasmids). The enemies in system shock 2 and Bioshock are very similar, except those in System Shock tend to be alot more fear inspiring and seem more real IMO. As for the setting, rapture is very classy, but the Von Braun is AWESOME - the helpless survivor aspect added to the immersion tenfold. If you like Bioshock, you will LOVE System Shock 2.
Luckily for us, some kind people have created mods that increase the level of details on enemies, weapons models, player models, and textures, allowing it to actually look semi-decent.
