Hello! Hey Bungie, I just had this idea, you know the exo zombies on COD AW? Well I was hoping we could do almost the same thing. We could pick to get either vex, cabal, fallen, or hive waves. You would basically be in a room with a door at one end, and then the doors would let the aliens out and you would fight them! You could either do it in private with friends, or do it with random people. Please comment with what you guys (Not just Bungie) think of my idea! :D -BananaPower978 (Founder of The Liberty Of Light clan.)
