i would say no, since a battle royale game relies on a zone to move everybody towards each other, last man standing wins and the games aren't detrimental to the next
I think 50/50. Battle Royale is where a number of players fight against each other in an enclosed space. Survival is where players have to find a way to survive in that area.
sort of? more of a survival game than a battle royale i guess. there's no rings and its heavily focused on looting for profit rather than just simply winning fights
