A huge return to form of the COD series, Black Ops 2 has taken the 'Great' that was left behind by Modern Warfare 2 to 'Amazing'. On the surface, same game engine and all, it seems like another Modern Warfare 3 case (admit it, MW3 sucked), but what made the game so enjoyable was not the game engine, but rather the little changes that they made to the game itself.All will be explained in detail below.
The characters up for use in this game are Alex Mason, Frank Woods and David Mason, son of Alex, which is more or less the main character in this game. Again, I said 'more or less' as the Campaign, in truth revolves around Raul Menendez more than any other character. All the 3 playable characters are connected to Menendez in their own way, and at the end they intertwine in some sense. Any decisions you make in the Campaign can either benefit you, or bring you harm. Treyarch has sucessfully created a Campaign where its not just any story, but a story which is created by the gamer through their hunches and decisions throughout the game based on how they feel and acting on that feeling, just like in real life.
The Campaign has also gotten a more Multiplayer feeling to it, with players being made able to actually choose their weapons before the mission starts, but with restrictions (unable to use modern weapons in 1960's era etc.).
One of the best things that beginners can expect from this game is that there are finally bots(AI) available in Multiplayer(YAY!). from level 1-10, it is advisable for beginners to try out the bots matches and really get a good feel of the game before heading out for original PVP and not getting steamrolled in the process.the bots are highly intergrated, ranging from amateur bots that are easily owned to expert bots, which sometimes are not too bad. Treyarch has done a good job with the intergration of the bots system, and it really provides the beginners with a level playing field against players who have been playing this game for a long time.
There have been some new gamemodes introduced other than the classic TDM,CTF,S&D. There's Hardpoint mode, which sorta reminds me of King Of The Hill(KOTH) mode from Team Fortress 2, where you capture a point and hold it until a certain score is reached. It feels somewhat copied from other games, but that has not stopped me from enjoying it.
Verdict:a HUGE innovation from Treyarch. Having to take big strides and making bold plus risky moves really do pay off. Do buy this game.
