The same goes for the musical score which helps create the stunningly tense environment. The above mentioned rain and snow effects are visually impressive as well. New features include new weapons and even a sniper mode. The tangos' artificial intelligence has been bumped up too. Play the game on the hardest difficulty setting, or elite level, and the tangos will come out to investigate any little sound.
Tangos are very smart and accurate making for a more challenging game.
Try playing without auto-targeting for an even greater challenge. RS is a blast in multiplayer, too, if you've got a reliable connection. My first six or seven attempts were miserable failures due to technical difficulties and not my own ineptness. My PC locked up or the game itself lagged to the point where play was just not worth the trouble. Multiplayer gamers with 56K connections must be patient to work through these issues and they will be rewarded.
