The reason its not fun anymore is because the infected can easily out-run the survivors, and that makes the game short and boring. When its just you and a buddy sitting in a good spot with 16 other people rushing towards you, things can get intense for a good while, for both teams. Which makes the game fun.
Take the throwing knifes away, and get rid of the death barriers.

If we can tweet to Robert Bowling about Drop Zone, and get that back, I think we can tweet him about this issue, and hopefully he'll get something done.
If not, then simply boycott Infected!!!

I don't mind the death barriers it will stop the impossible spots I guess
But throwing knifes just ruin it there so anoying as well as people getting knifed and leaving -.-

Drop zone is back :y:
And the playlists are updated so its: 3 Throwing Class modes and 3 Tactical Knife modes. - from You must login or register to view this content.
But the problem i have is.. the tactical knife mode has sh*t guns & crap maps.. they should balance it out & let use play on all maps both on the throwing knife mode + the tactical knife mode. plus give the same guns to both modes.

I can`t stand playing on the tactical knife mode.. the guns are terrible and the maps havn`t got any good spots to defend in

Balancing it out & giving the same maps+same guns to both throwing knife+tactical knife modes would make infected playable again..
