The weapon wheel is back!
I don't know about you, but I love carrying more than just two guns. Sweet dude. I really hope they bring back the badass lobby system R1 had. Who cares if you can add people to PSN, it is so much better to add buddies for a specific game. There should be more interaction between players, bring back the chat too while you are waiting for a game and in staging. The squad system better be back too. I HATE having to hear what everybody says, sure there is mute in some games, but nothing beats a squad. I also liked how you had to hold down R3 to talk to the whole team. I am sure it is wishful thinking.
Insomniac Games was experimenting, and obviously those experiments for R2 weren't too good.
R3 will be the last of the series I am sure, so make it good yo!
