The missions aren't particularly satisfying. Some of the more complex missions are great, like when you have to climb your way up a cathedral tower and snipe enemy soldiers as they rush your ally, who's stuck waiting for transport. The problem is that most of the missions are rather anticlimactic. You'll spend a long time fighting through as many as six or seven fairly simple but time-consuming objectives, only to have the final objective be something as simple and unexciting as walking to the ex-filtration point, unchallenged, so you can exit the level.You have to play some time in order to be a good sniper but i have managed you will manage to.
