Fun gunplay and plenty of targets.
The game does a great job of making you "feel" your guns firing. I'm not talking about controller vibration feedback but the visual appeal to firing the guns. There is a certain satisfaction to burning through your 30 round clip in a matter of seconds successfully downing two enemies then a third comes around a corner guns blazing at you and you have to get behind cover to reload and popup to return fire. This happens a lot and is very exciting all because the guns are presented so well.
The levels are quite large and take a while to work through. The lesson I have learned the most is to take my time. Numerous times I am repeating a checkpoint by getting too excited praying and spraying to be gunned down right before I hit the next check point. So, I have slowed down and have had my team mates use flash bangs, smoke and frags to help me. Your AI team mates are pretty good in my opinion. A few times I sent them into an area first because I couldn't clear it and they made mince meat of the enemy with lethal authority.
By far my favorite feature is the single player experience points allowing you access to unlockable items such as armor, weapons, camo schemes and gadgets. What you unlock in single player stays with your character into the multi player experience. To my pleasant suprise the game picked up I had played Rainbow Six Vegas (the predecessor to RSV2) and gave me three unlocks right at the start calling me a "Veteran" (Sweet!). This helped a lot considering I can't hit the broad side of a barn with a battleship cannon pointing right at it... he he.
Althought I complain about the graphics not being up to current standards they are by no means ugly. After an hour or two of looking down the sight of your gun and watching the grenades fly you wont really care about nicer textures.
I haven't hit up multi player yet but if it is anything like the first Rainbow Six Vegas which I have heard its better then multi player will rock.
This is a great game with a great feel to it.
I highly recommend this game for tons of fun.
Have fun!
