As spies, you'll be equipped with familiar night- and thermal-vision goggles, along with a variety of gadgets. Mercenaries, on the other hand, are completely opposite in every way. Instead of playing in a restricting, third-person perspective, a first-person viewpoint allows players to scan rooms quickly for enemies; and electromagnetic sensors (detecting any sort of electronic movement, including the use of spy gadgets) and motion-based infrared vision are installed in their goggle set. While it's hard to visualize, with the disparity between each character profile, such differences will make your stay in Splinter Cell's multiplayer realm a very balanced one.
