I came up with a new zombies game mode named Streak.
It would be a mixture of MW3 survival mode, CoD multiplayer and zombies. You start off with M1911, every minute, one increasing wave will spawn every 45 seconds, your gun will get better (like gun game), you get kills and get killstreaks. Lightning Strikes, Stealth Choppers and Swarms (renamed to suit zombies!)
Once you've gone through the weapon cycle, you go throough a similar cycle with the same guns but upgraded. Then you get a cycle of perks however once you've got them you don't lose them. Tranzit's cornfields would be an ideal map for this mode or the golden gate bridge from Mob of the Dead?
WHAT DO YOU THINK?
