Just a few personal tips/notes before you embark on your final 24 hours!
I know lots of people want to play and just skip through the story as the story may not have been a huge role in the first game, but I highly encourage you listen to the dialogue. There isn't much mission text anymore and you won't need to sit there and read a page of text before going onto the next mission. That is all now presented to you in spoken dialogue. This brings up the new feature where you can move away from NPCs and they will pop up to your Echo box and continue on with what they are saying wherever you go, but make sure to listen, as the story is amazing. Anthony Burch, writer for Borderlands 2, knocked it out of the park. You guys will laugh as this is Borderlands and humor is always present in this universe but there are some very tense and serious moments as well.
So if you play co-op, take your time. It isn't a race and make sure to let your friends know that as well as some may attempt to speed through and interrupt dialogue with others as they run around hitting ever NPC. Don't let them

. The world is huge, explore all the nooks and crannies. The level design team did an amazing job in making sure to hide some fun things for you guys. Hit up all the side quests as you guys will get a freaking kick out of those.
Try to stay away from the spoilers on the internet. Make sure to enjoy it all and enjoy the moments you will experience.
Gearbox is the most passionate group of people I have ever worked with and I'm stoked that BL2 is finally coming out . We have barely scratched the surface with all the stuff we've shown to the press. You are in for a wild ride. Have fun
