If you removed the drop pods and Spartan armor, and made all suits marines, than maybe, just maybe.. this could have happened.
Making suits similar to a set of Mjolnir armor just by the looks would be extremly expensive. And drop pods really, what should they have been droped from, a plane? the cieling? Doing that every match would also cost much.
And how would this whole thing work? Because if this Halo simulation were to survive it would have to cost for the players. This would be so expensive that only rich people could afford it, and not normal high class people, but people with really much money to spend on entertaining.
And for protection, the players would have to wear helmets, of some kind. If these were costum helmets to the playground, they would get really sweaty and smell really bad after some months. Cleaning them would not be an easy task because if they were to cover the whole head like they do in the Halo series, the helmets would need some kind of soft tissue inside to keep them comfterable and safe to wear.
If people had to bring helmets, it would ruin the whole illusion of being in the halo universe.Wich I suppose was the purpose of these paintball battlegrounds you hope to make.
So in order to make this possible you would have to lower your ambition a little, full spartan-look suits for 2 teams of 4 would cost to much to become a reality for average people.
