The latest installment in the stupidly best-selling Call of Duty franchise, Black Ops carries on in fond memory of its predecessors, copying and pasting every aspect of the last game in the series, slapping a new label on the box, and laughing all the way to the bank. It's a tried formula that's worked to perfection for Activision and it doesn't look like they're planning to stop as shown by both this game and the Guitar hero series.
The single-player is tolerable, just as in all the other installments. I found the storyline to be less interesting than in the modern warfare line, but still dozens of times better than those in the WWII stories. There's a limit to the number of times you can kill Nazis and make it interesting. This game is staged during the Cold War and is made rather interesting by your encounters with historical figures from the times such as JFK and Castro. It feels grittier and gorier than the WWII titles and is distinctly inappropriate for younger audiences.
In my personal opinion, the multiplayer makes a pretty substantial improvement from its utterly broken and unplayable modern warfare 2 counterpart. Several of the obnoxious and useless weapons are removed and most of the broken ones have been nerfed to tolerability. While the typical game modes return including death match, domination, search and destroy and all the others, they've also added a few new ones called wager matches. In these modes you wager your COD points, which you use to buy new weapons, attachments and perks, against your opponents in a variety of new and interesting game types. While nothing ground breaking, these modes add a bit of variety to an repetitive experience.
As to the appropriateness of the content, the multiplayer contains material suitable for mature teenagers. Whereas the single player surrounds a military interrogation complete with shock treatments and questionable drugs, the multiplayer is devoid of any vices outside of violence. The gore and blood is toned down to near non-existence and there isn't even an ounce of sexual content. As long as you take care to monitor your teen's online interactions and make use of the parental safety settings on the console, your teen should remain protected from even the most horrible trolls and flamers.
Another online compatible mode that should be mentioned is the Nazi zombies mini game. This mode plays just like it sounds. You're dropped in a base filled with zombies and you've got to survive. Incidentally, the zombies are Nazis. This game mode is cooperative, with up four players and distinctly more bloody than the regular multiplayer. The most efficient method of exterminating zombies is to shoot them in the head, which explodes in a shower of blood and gory chunks. Blowing off limbs also slows the zombies down significantly, quickly littering the battlefield a wasteland of dismembered arms and legs. Due to the intense violence in this mode, I'd suggest limiting this game mode to those older than eighteen.
While nothing particularly new or different, Call of Duty: Black Ops is a solid first person shooter. If you haven't gotten sick of fragging nameless noobs with your friends, this game is certainly a candidate for purchase. If you're looking for an interesting single player experience, I'd suggest looking elsewhere, but the multiplayer retains what made the modern warfare franchise so huge. However, keep in mind that this game deserves its M-rating in many aspects, so parents need to keep tabs on what their children are playing.
