You have to find and play this game by any mean necessary!!
I bought it, paid a full 60 canadian bucks in a future shop, came back home and played.... and played...and played....and played.
System shock 2 hooked me. The gameplay was so fantastic that it kept me playing for hours and for days and weeks. This game belongs to the category we call FPS/RPG hybrids which means your sight is in first person and there is a character build-up system to it. SS2's story is set in a derelict spaceship overunned by parasitics creatures which borded it after it landed on a planet. You wake up with no memory of who you are or what's happening and a ''surviving'' crew member briefs you and gives you directions. And then... the adventure starts!
To complete your tasks you have an array of weapons, skills and enhancements which can be upgraded to you liking and to suit your playing style: you prefer hacking turrets rather than destoying them? fine. make sure to upgrade your hacking skills! You want to research creatures organs to learn how to kill them efficiently? Upgrade your research skills!
Without telling too much about it, if you've played games like Deus Ex 1 and 2 or bioshock and loved them, you'll be pleased by System Shock 2.
On the minus side, the graphics: they were already dated for the time, using the thief 2 engine, so today they're quite ugly.
If you're planning on getting the game, make sure you download fan stuff that make it look better like the Rebirth mod which changes character textures and others mods which enhance texture resolution. Make sure to look out for a way to make it run on WinXp: get this info on fansites.
