Black Ops or Halo: Reach?

I would say Black Ops because of the amazing campaign and 2 free nazi zombie maps! The zombies are also coop meaning you can play with a guest over at your house online!

I never liked the call of duty games as much because they reward good players, making them able to do even better, so the new guy gets stomped over and over again. The AC-130 makes it impossible to even take a step after spawning because the guy who found a way to climb the level can't be killed because no one can find him. Makes it really hard to get started. With Reach though all you get for playing a lot is cool looking armor. In COD you end up fighting tanks with better guns and better attachments than you simply because they have no life and have unlocked everything.

The older halo games lagged online, but with a good connection I only get lag in maybe 1 of 20 games on Reach.

But it really comes down to what you like. If you want realistic shooter with strategic movements and real guns, go with COD. If you want to fly, kill aliens and just in general fight against people on even footing as you, Reach is better. In addition, reach can be played casually, while in order to have fun with COD you have to play all the time so you can unlock good weapons so you can keep up with the spoiled 15 year old kids whose parents let play all day and night.

In Reach you can play the campaign with a Friend or the mode called firefight where you fight wave after wave of aliens. Overall the experience of each of these don't change with 2 people, but they are still fun.

Black Ops for the AMAZING online... Halo Reach Online is terrible.

I like Reach much better, I am addicted ^.^

Zombies! Left for dead bro its deh beast!
