@azezeB Some suggestions

1. Dead By Daylight. 5 people with one being the Killer so you can rotate that if desired.
2. Halo Infinite multiplayer can do 12 person parties for the “Big” map modes.
3. I believe Lego Fortnite also lets you have up to 8. It’s more Minecraft and not a Battle Royale at all.
4. Lethal company modded can support more than 4. That could be lots of fun.
5. Retro FPS like Quake from various years. Just as a small distraction
