Borderlands 2

Yes...

lol :D

No, you've been tricked.

What is Borderlands 2?

The Multiplayer, or rather CoOp, is what makes the game so awesome.

You play the campaign with up to 3 friends (4 people in total) and can do all the quests and raid bosses later together.

More people means stronger enemies (not only in terms of HP and damage) and better loot drops.
Plus most classes have team abilities in them somewhere what encourages teamplay a lot.

I thought it was lone wolf..:P

Only weaklings need friends )>' ')>

You can tell the level of your chars too. :P

Don't do Krieg with a mechro. That ***** keeps sending my Krieg into Fight For Your Life with their reflected shots. >:(

MY EYES... HURT

Can't beat this Siren

Although, you might prefer this

When did you start playing BL2? I think they release them on weekly basis
I just started playing and i hoarded around 30 of them from here

Common enough, I've built up 130 myself since last Christmas. You can always find new ones here.

It would be a waste to not use them, because if you don't use them they get invalid after a while, they are only valid for a certain amount of time.

If you activate them you get golden keys ingame where you can open a chest in the main city which always has guaranteed purple/purplepink items for your exact level.
It comes in handy when you have reached the end level and open the chest a couple of times, or can't find good gear.

In total I think you could get at least 35 keys with the active ones that are still around, plus new keys get dropped on the twitter sometimes for example, that only last for one or two days.
