Single Player doesn't quite cut it. Multiplayer is better than COD 4
Bad Company does what other online shooters fail to do: keep things balanced, keeps things fun.
-Intro-
You ever sick about when you get a game 3 weeks late, so you are instantly behind the learning curve of all the 12 year olds? You start playing online but everyone knows every little nook, every little cranny, and most importantly: every spawn point.
Too many games fall into the rut of rewarding their more experienced players with better guns and better powerups.
Now, let me say Bad Company does this, but not so much to make a gigantic difference.
-Review-
Bad Company, unlike COD 4 is concentrated on large scale battle. It is definitely made for Haloites that love "Big Team Battle." Bad Company's multiplayer is formed around a game that consists of "Attack and Defenders." That's pretty much it. No I am not kidding.
For the lack of other modes and games, Bad Company focuses on this mode and does what it does best.
Each mulitplayer game consists of the attackers trying to blow up the defender's crates in order to advance on to the next base. When the attacker is successful at destroying both crates the map opens up, the attackers take control of that base, and the defenders have a new base to try to defend.
Bad Company makes use of several classes: Assault, Recon, Demolition, Specialist and Support. Each class has a own unique way of evening the playing field. They did a good job of balancing each class to be able to counter another aspect of the game.
Like most of the Battlefield series, you can take control of any of the vehicles. You can call in air strikes on command, and you can now spawn on your teammates.
To this last point, I have never really liked "big team" battles before this game. The fact that you can spawn on a squad mate is awesome. Too many times in other games you get killed while on a "mission" with your brother and have to spawn back in base. Whats the fun in playin online with a friend if they are on the other side of the map while your stuck having to run 5km to get to him?
-Conclusion-
I'm rambling now.... So, there are several aspects of this game's multiplayer I hold in high esteem over many other shooters now-a-days. The single player isn't much to mention, but the multiplayer will keep you playing this game much longer than any other shooter on the market.
