Those hackers at Night Dive Studios have done it again, by re-releasing the original System Shock with a number of updates to make it work on modern PCs.
In a lot of ways, this re-release – titled System Shock: Enhanced Edition – looks a bit like the old System Shock Portable fan-made re-release, in terms of things it adds and fixes. Here, for instance, you’ve got support for up to 1024×768 resolution, or 854×480 widescreen mode. Mouselook support has been added, along with remappable keys (and three different profiles depending on your handed-ness), in addition to the usual truckload of bugfixes.
If you fancy picking it up (and, while I can’t speak to its quality, the original System Shock is a fantastic game) you can do so on GOG now for $7.99. It’s normally $9.99, but it’s dropped a couple of dollars for launch.
