The idea is to fix the problem when it's 10x1 in zombie mode (all the players go to the survivors).
Solution:
Give the Primary Zombies (players that were zombies from the beginning of the round) some advandage, like a special feature or a bonus weapon.
Survivors that get killed and turn into zombies shouldn't get this thing.
That would help a lot. Right now I will always go to survivors, because what's the point of going to the zombie team? I will become a zombie when I die anyway.
And players don't really play to survive. They play to get more kills. What's the point of beeing a zombie if you'll die 2 times and get 1 kill, when you can get 3 kills while beeing a survivor? The rank exists in cs2d you know...
For the "mass zombies" idea to work there shouldn't be kill/death information for zombie players not to fear death.
