I love duel welding in halo 3 and I think you should bring that back. Players should have some sort of an equipment like mines and gravlifts that would be cool.
I think that in halo 4 they should have up to 20 players so it can be 10 on 10. They should also have a mongoose and have a gun on it or have trap mongoose where when the person gets in they will explode.
If anyone wants to do 8v8 on halo cea message me because I want to celebrate 10 years of halo and put your gtag and red team or blue team, this is on nov 15. Halo cea 8v8 I hope will be a blast on november the 15th.
