The game is full of dark tones, which are good when slinking from one shadowy pool to the next. Really, there is just good contrast, which is an important part of the stealth action. The cool part comes when switching to nightvision or infrared, watching a dark screen bloom into previously unseen detail. One gripe about the in-game interface is that it sometimes feels cluttered. The mission objective especially seemed to pop up a lot and get in the way, and couldn't be "put away."
Sound is an important part of the gameplay in Splinter Cell Essentials. Depending on how you feel about screen real estate, you may like or dislike the sound meter, since it does take up plenty of space. Basically, the meter reads the levels of ambient sound, on left and right channels. The sounds you make register here, also. This is similar to the indicator showing the level of ambient light in your location. Both sound and light can give you away, but the sound helps most to give away the enemy position, which allows you to adjust your strategy. The cinematic cut scenes are excellent in every way, and there's a great story that plays out through the course of the game. We have Tom Clancy to thank for that.
