New features include an enhanced version of the "Persistent Elite Creation" system. Players can now customize their character with experience points earned in both single-player and multiplayer. There is also a new stat-tracking feature which observes how players choose to play, unlocking new weapons and equipment based on their playing styles. All of the old weapons from Rainbow Six Vegas will be in Vegas 2. There are 11 new weapons, 13 multiplayer maps, 2 new game modes, and a tweaked ranking system, as well as improvements to the online functionality to make it easier to find online sessions. In addition, players can now join matches that are already in progress which was a feature unavailable in the original version and players had to wait until the current game had finished until they could play.
