Since a lot of ne "big name" games coming out today are so bad and boring, I decided to give a new and improved SS2 a go again.
I started by installing these mods:http://www.systemshock.org/index.php?topic=4447.0
The graphics are now updated, and 13 years worth of bugs and small tweaks have been made. The result is spectacular...I was only going to "try it" yesterday but ended up playing through the med-sector, sci-sector and crew quarters. The music, atmosphere and feel of the game is still great.
I highly recommend it, it's available at Gog if you want to try it!
