Uncharted is good in all areas.
The Multi-player is a great addition to uncharted. it has many game modes and maps testing each one of your skills whether its close range or long range. uncharted 2 uses the money system instead of medal points which i think is a much better idea.
The first level puts you in a museum where you plan a heist and must go threw the stage without being seen using the new stealth system. but after that its mainly shootouts and explosions.
the characters in uncharted 2 are fantastic. each of these characters make "cocky" remarks which actually puts a smile on your face while climbing up massive landscapes.
uncharted 2 overall is a must have and should win game of the year for 2009. if not, then i don't know what the judges are thinking because they would be crazy not to give GOTY for uncharted 2.
