Gears of War 4 Split Screen Hordes?

I want to know if you can use a guest account on Xbox Live to add a second person to play horde with or do you need a second Xbox Live account to do this?

Solution 1:

Splitscreen is supported in all the coop modes for Gears of War 4 and even online.

You should not need a second Xbox Live account. I've never seen a game do that for splitscreen. Usually, the second player assumes the first players name with a number in parentheses next to it indicating which player they are.

Solution 2:

yes you can play split screen horde online with a guest account the guest player will show in game as your gamertag with a (1) after just like it was on gears 3
