User blog:Wontbackdown/aliens or zombies?

in the e3 stage demo when mark lamia was asked about zombies he said that they wanted to do something different for the co op campiegn suggesting that it could be a different type of survival mode or it could be diferent types of zombies some could be big some could have a special abilities and some could be explosive.one thing that they need to put in the survival mode is a zombie wave counter showing you how many zombies are left in the round making it easier to make a crawler.and after reading all of your zombie posts i realized that you would like it if your player could climb up walls.they should also add guns that you can buy with atachments already put on.and make some new power ups. what are your ideas for power ups guns zombies or other zombie related things
