Can anyone help. I can not play online at all except bymyself in the coop. even then my guy does not work. will not go up against a wall or peek around corners. I cant sneek around at all. the droan does not work. when try to log onto any game it starts to connect then say system error session no longer available. but when you check the session is available. any help would be great. I have completed the game and want to play online. all my other games work online.

I'm not sure about your connection issues but I know that the controls you are talking about are different in multiplayer.

You do not hug walls or peek corners in multiplayer. The best you can do is run up to a wall/corner and hold the lean button down(I'm not sure what it is on the PS3) and lean out left, right, or lean up a little.

As for the drone you might want to mess with the map and the d-pad to issue orders to it. You will probably figure it out.

well that explains one issue thanks
