[quote name='crunchewy']I, so far, haven't figured out how you even set 2D in an online game. Though it occurs to me what the answer is. Do you set 2D while the team selection screen is up? I was always setting 2D after the game started in single player games, but that doesn't work in online. I've wanted to play in 2D, but so far only started 3D games.
Incidentally, when in 3D, if you change the perspective, does the other player see the perspective change too? I not infrequently hit that bumper accidentally and I was worried I might be messing up my opponent in doing so.[/QUOTE]
In online play you can't switch back and forth. The way to go into an online game in 2D, you need to change your settings on the main menu before you start the game. I think that's the only way to change it. Once your default is set to 2D then the online games you host will be in 2D.
