Play PvE or PvP: Solo Start with Bots | EA Forums - 12909480
You can start it yourself, no matter how few people join, and the bots use the vehicles and play the objectives. No matter how many people join, there will be 12 bots on each team minimum. The map rotation is listed, and, as host, you can skip to the next map at any time. You get rank XP and battlepass XP, but you don't get weapon unlocks or challenge progression at this time.
For some reason, BattlefieldPortalOfficial (or whatever name they decide to use at any time), can publish a pistols versus defib server and get full progression, but other servers don't.
