I think a battle Royale would be cool because instead of a team based game it could have more thinking for yourself kind of aspect where you can choose to team up with someone or play by yourself, also everyone can hear your voice on surround if they are close enough so there are funny interactions and could boost sales of the game immensely. As a person who plays many fps games I would love to see a less bland game where all there is to do is play the objective and get kills. Kinda like Fortnite but more interactions between people. You open chests to get guns and mags and the ammo system you have currently is perfect because you can pick up individual mags instead of individual ammo. Also, on a side note, I would force everyone I know to get a pc and drop with me because it's the perfect experience
P.S. You could start with a hammer
