The COH franchise is my favorite of all time. Relic have somehow captured the intensity of the world wars in this wonderful series.
COH2 does not make a whole lot of changes to the overall game mechanic but introduces Truesight and weather as changes in COH2.
In the single player missions you play on the Russian side against the Germans. The 14 missions are varied. Graphics remain top notch with their new engine.
COH2 also introduces an RPG element where you gain experience and unlocks as you progress. There is also a Theatre of War mode which allows you to co-op with other players etc. Tons more to explore after the single player missions.
