Halo 5 will be the first halo to not include a sofa co-op. This comes a few hours after the news that 343 mistakenly told GameInformer that you would not need Live gold in order to play co-op with your friends.
This news has come as 343 has stated that the game will feature 60fps instead of the local co-op feature that has been loved since Halo 2.
Is this a bad thing? Personally, I loved playing co-op with my friends on the same screen. But was often more likely to use Xbox Live Gold anyway.
Only time can tell if this is the better decision. I trust 343 in saying it is the correct choice.
