Battle Royale alternative: BR gamemode lover, Similar gamemode like on fy_pool_day(CS 1.6): Team version.
Survival and Co-op Survival: Competitiv/Casual with enemies(soldiers, mutants), when you will kill, get moneys for buy better weapons a equipment.
Survival TDM: Classic TDM with bots, but extended time, because big map.

BTW: I don´t play Battle Royale games, I like Conquest in Battlefield or very good TDM.
