Del the multiplayer is a lot of fun. I was going to avoid it as I thought I'd be terrible at it, and I was at first xD I was hugely taken back by just how fun the multiplayer is. If you've done any of the N7 missions those are the standard multiplayer maps and on Bronze difficulty you won't have too much of an issue even if you're absolutely terrible. If you've got Voice Comms turned off multiplayer is just essentially single player anyway except the other 3 characters are being controlled by people and you have no idea if they're yelling "you suck" or not - though in all honestly I hardly ever hear people say anything let alone actually insult anyone. Give it a shot, you might be as surprised as I was.
