Not groundbreaking, but the next greatest thing. You will not be disappointed.
Some people say that 3rd person shooters don't give you the "experience". GRAW 2 gets you into the game. As you are hit you react accordingly. Bullets whiz by; In quiet city streets a sniper can really scare you.
The first thing you notice about GRAW 2 is the graphics. Even on a tube TV the graphics are stunning. Sound effects have improved as well, along with sound quality.
Unlike the GRAW 1, your teammates play a big part in this game. They will not stand in the open and shoot in front of 5 enemies, they use cover. An added feature is the ability to see from you support's point of view (drones, tanks, helicopters, and teammates). You teammates will tell you information aboutthe environment like "I see 3...no 4 targets. Four targets captain; what do you want me to do with them?"
Weapons have good detail, but reloading looks bad. When you reload, you simply move your hand onto the clip, to your vest, and back, and it makes some noises.
Campaign is painfully short and offers few achievments. The storyline for the campaign picks up right after GRAW 1's storyline. The same theme is present.
Multiplayer is great, with great character detail, little if any lag, weapon choice, and waiting lobby simplicity. The bulk of your achievments will come from multiplayer.
