I've played a few online matches, but standard deathmatches and FFA are actually closed in. The open map game is actually Free Roam where you're free to do whatever you please. While killing each other isn't NEEDED...it's very possible to start your own shootouts where ever you want, and still earn EXP.
That being said, though. You still get more EXP for working together in Free Roam, and more from playing the boxed in matches because they offer bonus exp for little things.
