Since there's no trading system, why not do a wager game of keeping the enemy players loot/weapons. Do it 1v1 style and there'll be a big screen showing who is against who. They wager their best weapons and 200 glimmer (currency idk) and fight up to three rounds. 6v6 works like 1v1, top three players on each team wager their weapons and cash. Losing team will lose their wager and so on. I just had this idea from playing COD BO1
