I dont know lists exactly but im a big battlefield player and ive rented a server to test it.
-not sure if you can set no spawn
-YES you can make respawn times longer or shorter (even can change how much time ppl have to revive a fallin man if i recall)
-last yes you can make them private. You can make it unranked and set to private with a password to invite your friends. or make videos whatever you like.
any other questions i might be able to answer just ask
I believe it has to be in a unranked game mode and its not exactly in time they let you change it in % intervals. 10%-300%, the normal time is 100%.How long can you make the respawn times? Are there any amounts that are ridiculously long?
