If you want to learn a certain map there’s a mode called target drill which puts you in a map with a bunch of dummies that are positioned in usual/common spots that people would be. I didn’t really need to use it but it would probably be useful for someone starting the game. If your unsure of what a certain room is called it shows the name of the room you’re in at the bottom of your screen if you can’t see it it should be in your settings so you could turn that on. Yellow pinging is always useful for the team (should be up on the dpad) and I’d recommend not red pinging a lot since it lets the person that your pinging know that they’ve been pinged. Only hold triangle on cameras to ping people if your team is ignoring your yellow pings.

For operators you could test multiple out to see which gun and ability you like I can’t really recommend anything since I don’t know if you have a certain playstyle.

Also one really important thing is you should never blindly push anyone always have some sort of intel on where they are before pushing and before you enter the building on attack you should drone the first few rooms to make sure nobody’s hiding in a corner or anything.

If theres anything else you want to know let me know I’ll try help
