Shoot mode is akin to Thief 's interface, with added keys for changing and reloading ammo types. Use mode is reminiscent of Diablo 's inventory screen, with options to view stats and mission data. That's extremely important, too. This game is easily one of the most interactive titles I've owned in my 13 years of gaming. It's also highly immersive.
Animation is fluid, and the textures are colourful and detailed.
Lighting is fine as well, and applied in ways that reminded me of the Alien films. Audibly, the game is downright disturbing, and I mean that in the best possible sense. The sound effects are chillingly realistic you'll jump out of your chair the first time a cyborg midwife decides to attack you, or an annelid egg erupts in your face. Gamers lucky enough to have a sound card that supports EAX will hear these sounds in three dimensions, properly echoed and reverberated. Infostream Computer games aren't normally known for their intricate plots, but this is another area where SS2 excels.
