Rainbow Six Vegas 2 is a decent and solid game.
Rainbow Six Vegas 2 follows the footprints of the first one. Not much is new, but a lot is enhanced.
I wont touch onto the story of the game because it was rather dull and uninteresting.
Basicly you play as a squad leader with two people under his command. You are able to order them around and decide where they move and who they shoot at first. You can put them in either infiltration mode, which makes them more passive and would rather return fire than give it. The other mode is assault mode. This mode will make them shoot and kill everything that moves, except hostages that is.
A cool and very useful squad feature is the abillity to order them to stack-up outside a door then either breach and clear with the use of grenades or an explosion to open the door and stun the enemies inside. Your team of elite soldiers are very skilled at taking down enemies quickly and if needed, quietly. If your teammates recieve too much damage they will fall down to the ground, and when that happens you have a little bit of time to heal them or get your remaining teammate to heal him.
The maps and campaign play similary to the prequel (Rainbow Six Vegas). Linear and scripted combat, but it does give you some freedom to choose how you want to fight your battles. Well, the freedom you get is often to choose if you want to enter a room full of enemies on the second floor or the first floor.
The best playing experience in this game I got in the beginning till about a bit over halfway through. From there on you had to advance alone through dark, high scripted and rather boring levels. The later part of the game takes everything that is Rainbow Six and throws it to the ground and stomps on it.
You have a wide variety of weapons at your disposal as well as equipment like nightvision and thermalvision, which are both very useful in the later stages of the game.
