To win in poker, you need to have a better hand than your opponent, or at least convince them that your hand is better than theirs by successfully bluffing. Every hand in poker is ranked, starting with a pair and increasing all the way through to a royal flush.

Each hand has a rank, which is compared against the ranks of other hands participating in the showdown to decide who wins the pot. In high games, like Texas hold 'em and seven-card stud, the highest-ranking hands win. In low games, like razz, the lowest-ranking hands win.

Modern Warfare 2's campaign is the perfect length, actually. Call of Duty: Modern Warfare 2's campaign is a brisk five-and-a-half-hours. I was sightseeing on that playthrough, too, because the game is gorgeous.

The Modern Warfare 2 campaign has 17 missions, and as with previous Call of Duty campaigns, the action is split across various continents and gameplay types as it jumps between the perspectives of multiple characters.
