In the single player campaign to do and redo. It is certainly short, but the level design is so rich that we can find a variety of ways to get through the levels. The script is worthy of a thriller. Moreover, as always in the games stamped "Tom Clancy", the choice of weapons and their sensations are pleasant and influence the gameplay.
The game has a very good life if you count all the game modes included: additional campaign coop modes of Hunter, Confrontation (great one), Territorial Defence, Infiltration, playable online.
The only flaw in my opinion the game is a weird AI often too sensitive and which results sheet in the air infiltration; and then yes, the game is completely "action". Sometimes we see enemies through walls and doors! Rather hassle to get some "Success" ("hunter Perfect" !!!)
Otherwise, good graphics (not exceptional either), rich and taking gameplay.
