I think it would be fun if someone made a gamemode like this.
first 5 minutes normal zombies that walk slow with average damage appear.
10 minutes crimson head zombies the running zombies with high damage (low amount of them mixed with normal zombies)
15 minutes lickers fast moving average damage (mixed with normal/crimson zombies)
[Lickers can crawl on walls and can grab you with their tongues]

20 minutes hunters fast moving very high damge (only 2-4 ever two minutes still mixed with normal/crimson zombies and lickers)
[Can run really fast..and take your head off with 1 hit.]

25 minutes resident evil boss such as the tyrant monster, william birkin or nemesis
[The bosses have alot of health and are very strong!]

Games extras
T-virus cure - Removes your infection level from zombies [With everybite you increase infection by 2% and once you reach 100 you turn into a player zombie.]

First aid spray [ Cures you too 100%hp]
