Anybody want like an infinite survival mode, and the higher you go the better chance for reward? Gear, guns, etc. Edit* Every specified amount if waves a boss could appear. Even further when challenges appear you can bonus and can possibly add to your chance percentage of getting gear. Edit* What do you guys think some cool challenges would be? For example Wave 5 challenge: use only snipers Wave 8 challenge: do not miss one shot Wave 9 challenge: do not scope in with any weapon. Each challenge can be random, not specified to a particular wave, however there will not be challenges each wave. Which waves have a challenge should be randomized as well.
