You do not need Live to play horde.
you probably don't need Xbox Live for beast mode, just as you didn't need Live for horde mode on Gears 2
No. All you have to do is beat gears 1. but unless your gonna be doin wingman, elimination, or some other form of non-horde multiplayer by yourself (or system link/local) there is really no point. you can't use RAAM in campaign. or on horde.
Gears 3 does in fact need xbox live to play multiplayer, but not for experience. Also, you can play multiplayer locally on Gears of War 3 via system link or on 1 console.
you will need 5,000,000 cash in horde and you get the big money to onyx
no
First, you'll need to make sure your isp is fast enough for xbox live. Then, create an xbox live profile on the xbox and add money either through a credit card or prepaid card from a store. After that, you should be able to play Gears online.
yes you need live and in fact you need live gold membership to play co-op with someone else on a different screen but no if you are talking about split screen if you are the only profile on your xbox just make another profile (doesn't need to be xbox live) and have the second controller sign in to that profile
you need to have xbox live
