Singleplayer - 9
The Singleplayer of Black Ops is awesome. Treyarch did another great job with the Singleplayer campaign. Voice actors, characters, levels, are all brilliant. The story of the Singleplayer had a fairly good length and good detail for the player to understand what's going on there. Graphics are also perfect, and with the addition of 3D graphics, one could think that he is on the battlefield himself. The things that I didn't like in the game, mostly are the disorienting environments, and the need of the player to be rapid in certain objectives, as some new players may get frustrated at this. Another bad element of the game is the "auto-pilot", in which the game basically prompts you to do something, and even if you don't actually do it, it still does it by itself, leaving you think that you did it yourself.
Multiplayer - 9
The Multiplayer component has a lot of things too, like the other Call of Duty games. Treyarch has taken a lot of measures to prevent a lot of things. Perks that were called "too tough" by other players were taken out, under-barrels have been restricted to be used along with another attachments, "easy" quick-scoping has been completely eliminated, as Sleight Of Hand Pro doesn't affect snipers. The addition of currency was very good, as now people can't start equipping everything they see on their way without some hard work. Wager Matches added a gambling element of the game, as it has a cost to get inside one, it has 4 game modes and only the top 3 players get paid. Gun customization is superior, every detail, from attachments to appearance and color can be customized. Combat Training, which uses a separate leveling system, features bots versus you, but it still needs an online connection to operate.
Zombies - 8,5
Zombies are good once again, also there are again a lot of clues to discover about the back-story. Zombies return creepier and all-new, with the 4 characters from World At War returning, and new levels, with one of them having new characters. An amazing easter egg is also a new way to see the zombies, but of course, I won't spoil it. The PC version lobby finding is a bit of a trouble, and also there are a lot of people doing infinite ammo cheats, glitches, etc. Also, there is a bit of lag, but it's good overall. It's disappointing to see co-op campaign not being here, as it was very fun to play campaign with your friends.
Final Rating: 8,8
One of the most anticipated games, but it has it's flaws. It's very good overall. Multiplayer introduced enhanced gun customization, and single-player and zombies were fairly good. Recommended for Call of Duty fans.
