This is supposed to be a sequel and most of the time it just doesn't feel like one.
Despite the downsides, however, Vegas 2 is a challenge in single-player and offers a fair choice of maps. New additions are a welcomed sight indeed, providing new weapons, exp. points, ranks and so on. Multiplayer is bound to keep you occupied and the fact that you can overcome battle situations in a unique way each time, offers a solid amount of replayability.
