Can you weapon change while in the middle of a multiplayer map?

Is there only one multifplayer mode right now. I only can click on obj games. What are the multiplayer modes?

send me a psn, xFLYNNx, I've got a mic, I've got several people coming over to Brink for about a week to make gameplay footage, looking for people to play against. Is there a list of psn's to get some full room scrims going?

Um, go to a command post. You can even change your class.
